The breast ultrasound examination should be performed with a high-frequency transducer of 7.5 MHz or higher. A linear array converter is preferred. A spacer pad can be used to assess superficial lesions. The patient should be placed in the supine or supine position with the ipsilateral arm overhead. The chest is scanned in the transverse and sagittal planes or in the radial and anti-radial planes. The retroareolar area is assessed by tilting the transducer in several planes to avoid shadowing

Normal brush anatomy

The skin is perceived as an echogenic layer up to 3 mm thick. Breast tissue lies deep under the skin and varies in appearance depending on the overall density of the breast and the distribution of fat and fibroglandular tissue. Unlike other parts of the body, the fat in the chest is hypoechoic. The dense breast tissue is echogenic on ultrasound (Fig. 1). Solid masses are usually hypoechoic and care should be taken not to confuse them with an island of fat surrounded by dense fat

cystic lesions

Ultrasound is 96% to 100% reliable in diagnosing cysts [12], [13], [14], [15]. In the 1970s, ultrasound reduced the number of biopsies for benign masses by 25–35% by reliably identifying simple cysts [15], [16]. A simple cyst is defined as a thin-walled anechoic lesion with sharp anterior and posterior borders and posterior acoustic enhancement (Fig. 2). Biliary artifacts can result in linear internal echoes in the anterior portion of a cyst [15]. A suggested lexicon for breast ultrasound

Doppler ultrasound without contrast enhancement

Although grayscale ultrasound features are helpful in distinguishing benign from malignant solid breast lesions, a significant number of breast tumors do not present the typical expected ultrasound image [39], [40], [41]. Angiogenesis is defined as the formation of new blood vessels by the sprouting of capillaries from pre-existing microvessels [42]. The formation of these new, abnormal vessels is associated with an increased risk of malignancy [43]. These concepts of

tumor size and grade

Ultrasound cannot accurately assess the size of a tumor and usually underestimates its true size [64]. The tumor grade cannot be precisely assessed using ultrasound either [33], [47], [59], [65]. However, one study found that high-grade invasive ductal carcinomas were significantly larger at diagnosis and more likely to have better-defined margins and acoustic improvements compared to low- and intermediate-grade tumors [66]. Some researchers theorize that the improvement is due to an increase

Fine needle aspiration biopsy and core needle biopsy

Provided a lesion is visible, performing an ultrasound-guided aspiration, biopsy, or localization offers certain advantages. The lesion can be visualized at any time during sampling, ensuring accurate needle placement. The procedure is easier for the patient because they can lie supine or slightly inclined during mammography or stereotactic procedures instead of upright or lying down. There is no radiation, which is especially important for pregnant patients.

Biopsy with fine needle puncture in the breast

Microcalcifications on ultrasound

35 to 45% of non-palpable breast cancers detected at screening show up as clusters of microcalcifications on mammography [105]. Higher frequency transducers allow us to better detect mammographically isolated microcalcifications with ultrasound (Fig. 16A, B). A study examined 76 patients with 7.5 MHz and 10 MHz transducers and found an increased visibility of microcalcifications by 45% to 74% in benign breast lesions and 91% to 97% in malignant lesions [106]. The

screening for breast cancer

Mammography is the only widely accepted imaging method for early detection of otherwise hidden breast cancer. Many lesions cannot be seen on mammography. Three older studies reported a cumulative total of 236 incidental ultrasound-detected lesions and found no malignancy based on biopsy or long-term follow-up [13], [111], [112]. Recent studies have shown that ultrasound can detect adventitious cancers in asymptomatic patients and in patients

Breast implants

MRI imaging is currently more sensitive and accurate than ultrasound in assessing silicone implants for fractures [115]. When MR imaging is not readily available or cannot be performed (due to claustrophobia, internal metal clamps, or other reasons), ultrasound is an alternative. An intact implant without a fracture appears anechoic with an echogenic anterior wall on ultrasound [116]. Implant ruptures can be classified as “intracapsular” or “extracapsular”, with the former affecting an intact implant

The man's chest

Breast cancer in men is rare. It accounts for 1% of all breast cancers and only 1% of all malignancies in men [121]. Ultrasound has been used to assess male breasts [122], [123]. There is an overlap in the occurrence of benign and malignant diseases with separate mammography and ultrasound; However, it is believed that combining these modalities improves accuracy. Gynecomastia is a common benign breast disease in men. Men with this condition usually show symptoms of a lump or


Ultrasound is an important imaging technique used to evaluate the breast. One of the most common uses of ultrasound is to differentiate between benign and malignant breast disease, primarily with grayscale ultrasound but also with Doppler ultrasound. Another common use is to provide guidelines for interventional procedures. Less common uses include assisting in breast cancer staging and evaluating patients with implants. Recently, there has been interest in using ultrasound to screen for asymptomatic diseases

    • Development and measurement of a range of process and outcome indicators for breast cancer

      2012, chest

      Quote excerpt:

      Mammography remains one of the most important tools for evaluating a palpable breast mass or other signs of breast disease. Ultrasound has emerged as an important tool for assessing a palpable mass in women with dense breasts and/or as an adjunct to mammography.9,19,20 EUSOMA recently proposed a rate of 95% of women who undergo preoperative mammography, a physical Investigation and other investigations subjected ultrasound as a target to be achieved.16

      The aim of this study was to develop and measure a set of indicators to monitor the quality of breast cancer care, make comparisons over time, and support quality improvement for all physicians and centers involved in the care of women with breast cancer.

      Quality indicators were identified based on a systematic literature review and the 2010 Belgian evidence-based clinical practice guideline. The selection process involved a panel of experts who assessed the reliability, relevance, interpretability and usefulness of each indicator. The quality indicators were tested based on data from the Belgian Cancer Registry linked to application data for all women diagnosed with breast cancer in Belgium between 2001 and 2006 (n=50,039).

      The selection process resulted in a final set of 32 indicators. Of these, 12 were measurable using the available data, while one indicator was measurable using proxy information. Five-year relative survival was 98%, 87%, 68%, and 29% for pStage I, II, III, and cStage IV, respectively. Five-year overall survival improved between 2001 and 2004 for pStage II, III, and cStage IV easy. Of the women treated surgically, 60% received breast-conserving surgery, 85% received adjuvant systemic treatment, and 86% received postoperative radiation. 80% of women treated for breast cancer had at least one mammogram within a year of their last treatment.

      The current study shows that it is possible to develop a multidisciplinary set of quality indicators for breast cancer. Using national cancer registry data linked to claims data, 13 indicators were measurable, with results broadly consistent with other studies in the field.

      Quote excerpt:

      Before using MR imaging in such cases, ultrasound should be part of the initial imaging assessment. Ultrasound is a very useful tool in the assessment of mammographic lesions, particularly in patients with dense breasts.58–60 However, ultrasound can be limited when the lesion in question cannot be identified with certainty in two projections.55,61

    • Palpable and non-palpable chest masses

      2008, Ultrasound Clinics

      Quote excerpt:

      Thoracic US must be performed with a high-frequency linear transducer of 7.5 MHz or higher. The patient should be placed supine to minimize the thickness of the chest area to be examined.1 The patient's ipsilateral arm should be over the arm.

      Breast ultrasound (US) is useful not only for identifying the cystic contents of breast tumors, but also for characterizing the solid masses. The BI-RADS US Lexicon, like the Mammography Lexicon, provides standard terminology and scoring for breast US reports. In this article, the author examines the different types of cysts and solid lesions and how they can be treated. It focuses on categories 2 through 6 of the BI-RADS final ultrasound assessment categories in the American College of Radiology Imaging Network Protocol 6666, which indicate how and whether cysts and lesions should be treated by biopsy or aspiration.

      2007 Magazine for Nursing Professionals

      Inflammatory breast cancer is a rare and aggressive form of breast cancer. It begins quickly and clinically resembles mastitis. We are talking about a patient who came to our practice with apparent mastitis, which eventually turned out to be inflammatory breast carcinoma. An overview of the typical clinical presentation, diagnostic imaging findings, biochemistry, treatment and prognosis of the disease follows.

    • BIRADS ultrasound

      2007, European Journal of Radiology

      Quote excerpt:

      Ultrasound-adapted software is evaluated for automated characterization of ultrasound abnormalities according to the BIRADS US lexicon with immediate recommendation of an assessment category (Fig. 1-10). To assess the sensitivity and specificity of breast imaging studies in screening and diagnosis, histological results from guided and surgical biopsies should be collected and reported to the referring physician and radiologist [22]. The development of digital imaging enables the radiologist to compare histological results and archived images with the patient record, creating an optimal tool for medical education.

      The fourth edition of BIRADS Mammography was published in 2003 and is now linked to the first editions of BIRADS Ultrasound and MRI.

      BIRADS™ is a diagnostic assistance system that is increasingly used worldwide and will soon be implemented directly on mammography and ultrasound machines.

      The BIRADS scoring categories allow a clear synthesis of the descriptive data resulting from the use of the lexicon, inviting the radiologist to a reasoned, objective and less intuitive step. They give the radiologist and the referring physicians a need for action and responsibility in agreement with the patient.

      Management of BIRADS 3, 4A, and 4B Lesions Diagnosed as Pure Papilloma by Ultrasound-Guided Core Needle Biopsy: Is Surgical Removal Required?

      Academic Radiology, Band 26, Ausgabe 7, 2019, S. 909-914

      There is no consensus on how to treat papillomas due to differing upgrade rates in the literature related to variability in the studied populations. Specifically, we examined the enhancement rates of pure papillomas diagnosed by ultrasonic core biopsy (UCB) using spring-loaded (SLB) and vacuum-assisted (VAB) biopsy devices in patients with a low to moderate pretest probability of malignancy on imaging.

      From January 1st, 2008 to June 30th, 2016, 227 patients with 248 pure papillomas of classification BI-RADS 3, 4a and 4b were diagnosed by UCB and underwent surgical removal or a clinical and/or imaging follow-up examination. Image features, biopsy device, and final pathology were documented.

      177 lesions were biopsied with SLB (14 gauge) and 71 lesions with VAB (9-13 gauge). At surgery, the upgrade rates for high-risk lesions and malignancies were 14.3% (22/154) and 1.9% (3/154) for SLB and 3.5% (2/57) and 0 for VAB, respectively % (0/57). (p<0.05). The combined rates of surgical upgrades for high-risk lesions and malignancies were 11.4% (24/211) and 1.4% (3/211), respectively. The overall rate of upgrades (including surgical and clinical and/or imaging follow-up) to high-risk lesions and malignancies were 9.7% (24/248) and 1.2% (3/248), respectively. There were no ultrasound characteristics predicting an upgrade. The complete excision rate was 7.1% (11/154) for SLB and 19.3% (11/57) for VAB (p<0.05).

      BI-RADS 3, 4a, or 4b mass biopsy with UCB revealed an upgrade from a pure papilloma to a malignancy in less than 2% of cases. SLB came with major upgrades compared to VAB. Therefore, follow-up is a useful alternative to excision, especially in patients sampled by VAB. Excision may be considered when diagnosis of a high-risk lesion would change clinical management.

      Analysis of the effectiveness and accuracy of two vacuum-assisted breast biopsy devices: Mammotome and Elite

      Clinical Breast Cancer, Volume 18, Number 6, 2018, pp. e1277-e1282

      Ultrasound-guided vacuum-assisted breast biopsy (US-VABB) has recently replaced surgical biopsy due to its high diagnostic accuracy and low patient discomfort, and currently relies primarily on two devices: Mammotome and, more recently, Mammotome Elite (Elite). Our aim was to compare the effectiveness of these two biopsy devices.

      We performed US-VABB in 195 patients with Mammotome 8G or 11G in 130 patients and Elite 13G in 65 patients. Of these 195 patients, 95 underwent lumpectomy or mastectomy surgery for malignant lesions or lesions of uncertain malignant potential (B5 and B3), while the remaining 100 underwent close clinical and radiological surveillance for 12 to 24 months.

      Both devices showed high absolute sensitivity (96.2% for Mammotome and 83.3% for Elite), full sensitivity (98.1% for Mammotome and 90.0% for Elite), specificity (92.3% for Mammotome and 94.3% for Elite) and diagnostic accuracy (99.1%). for Mammotome and 95% for Elite) and meets the criteria proposed in the European guidelines. The overall underestimation rate appeared to be higher in the elite cohort (14.2%) than in the Mammotome cohort (3.4%) (P=0.02). However, none of the patients with a benign diagnosis (B2) experienced an event during the follow-up period.

      US-VABB is an accurate method for sampling breast lesions. Our study showed no major, statistically significant differences in diagnostic accuracy between the Elite and Mammotome systems, apart from a slight increase in diagnostic underestimation of benign pathology when using the Elite.

      Fetal heart defects: opportunities and pitfalls of first-trimester detection

      Seminars in Fetal and Newborn Medicine, Volume 18, Number 5, 2013, pp. 251-260

      Congenital heart defects (CHD) are the leading cause of death in infants from birth defects. In the past 15 years, with the shift of aneuploidy screening to the first trimester, a great deal of research has focused on early screening and detection of CHD. Early detailed assessment of the fetal heart requires a high level of expertise in early detection of abnormalities and fetal echocardiography. However, the detection of severe CHD at 11-13 weeks is influenced by its association with easily identifiable markers such as nuchal translucency measurement, ductus venosus blood flow, and tricuspid regurgitation, as well as a political decision regarding the goals of this scan and the allocation of resources needed to reach them. The use of transvaginal ultrasound and newer techniques should improve detection rates. However, the limitations of fetal echocardiography in the first trimester should be considered and in some cases mid-pregnancy follow-up is advisable.

      Restoration of early signal deficiency of axonal conduction by Guanxinning injection as a new therapeutic option for acute ischemic stroke

      Pharmacological Research, Volume 165, 2021, Article 105460

      Despite the high morbidity and mortality, effective treatment of ischemic stroke is still lacking, partly due to our incomplete understanding of the molecular mechanisms of its pathogenesis. In this study, we show that SHH-PTCH1-GLI1-mediated axonal guidance signals and associated neurogenesis, a central pathway for neuronal development, also play a crucial role in the early stages of an acute stroke model. Specifically, we studied in vivo the effect of GXNI on mice with ischemic stroke using middle cerebral artery embolization model and found that GXNI reduces cerebral ischemic reperfusion (I/R) injury by increasing cerebral infarct volume, neurological deficit score and neurologic deficit significantly alleviated cerebral edema, reversal of BBB permeability, and histopathologic changes. A combined RNA-seq and network pharmacological analysis approach was used to reveal the underlying mechanisms of GXNI, followed by RT-PCR, immunohistochemistry and Western blot validation. It has been suggested that the axon guidance pathway plays the most important role in GXNI action, with the Shh, Ptch1 and Gli1 genes being critical for brain protection. Furthermore, GXNI clearly prevented primary cortical neuron cells from being damaged by oxygen-glucose starvation/reoxygenation in vitro and promoted axonal outgrowth and synaptogenesis of damaged neurons, further corroborating the results of in vivo experiments. In addition, the effect of GXNI was significantly attenuated due to inhibition of the SHH-PTCH1-GLI1 signaling pathway by cyclopropylamine. Therefore, our study offers a new option for the clinical management of acute ischemic stroke by GXNI via SHH-PTCH1-GLI1-mediated axonal conduction signaling, a neurodevelopmental pathway previously considered for post-stroke recovery.

      Non-mass-like breast lesions on ultrasound: feature analysis and BI-RADS assessment

      European Journal of Radiology, Band 84, Ausgabe 1, 2015, S. 77–85

      Analysis of the characteristics of non-mass-like (NML) breast lesions on ultrasound (US) and determination of their corresponding malignancy and stratification of these lesion patterns according to US BI-RADS categories.

      One hundred sixty-four consecutive lesions were retrospectively classified into four types based on US features and the corresponding positive predictive values ​​(PPVs) determined. Clinical, imaging and histopathological findings were reviewed.

      Of the 164 lesions, 39 (24%) were classified as type Ia, 14 (8%) as type Ib, 39 (24%) as type IIa, 19 (12%) as type IIb, and 19 (12%) as type III and 34 (21%) as type IV. The PPVs for malignancy were 21% for type Ia, 79% for type Ib, 10% for type IIa, 58% for type IIb, 16% for type III, and 21% for type IV All NML lesions were classified according to their PPV into BI-RADS category 4a (Type IIa), 4b (Type Ia, III and IV) and 4c (Type Ib and IIb). Type Ib and Type IIb lesions had a significantly higher incidence of malignancy than the other types (P < 0.01 in each case). Lesions with associated calcifications, the presence of abnormal axillary nodules, or a mammographic finding suggestive of malignancy had a higher risk of malignancy (P<0.05 each).

      Ultrasound is helpful in clarifying the indication for biopsy of NML lesions. The US classification types used in our study provide reliable references for the NML patterns when stratified by the BI-RADS categories.

      Improving Mammography Workflow Efficiency with Machine Learning

      Journal of the American College of Radiology, Band 17, Ausgabe 1, Teil A, 2020, S. 56–63

      The aim of this study was to determine if machine learning can reduce the number of mammograms that the radiologist needs to read by using a machine learning classifier to correctly identify normal mammograms and select the uncertain and abnormal exams for radiological interpretation .

      Mammograms were used in a study dataset of over 7,000 women recalled for review at six centers in the UK's National Health Service Breast Screening Program. A convolutional neural network coupled with multitasking learning was used to extract imaging features from mammograms that mimic a radiologist's radiological assessment, non-imaging features of the patient, and pathological findings. A deep neural network was then used to aggregate and fuse multiple mammography views to predict both a diagnosis and a recommendation as to whether or not additional radiological investigation was required.

      (Video) Optimizing Breast Sonography

      Tenfold cross-validation was performed on 2,000 randomly selected patients from the data set; The rest of the dataset was used for training the convolutional neural network. While maintaining an acceptable negative predictive value of 0.99, the proposed model was able to detect 34% (95% CI: 25%-43%) and 91% (95% CI: 88%-94%) of negative mammograms to identify test sets with a cancer prevalence of 15% and 1% respectively.

      Machine learning has successfully reduced the number of normal mammograms that radiologists need to read without compromising diagnostic accuracy.

    What 3 ways is ultrasound useful in breast diagnostics? ›

    • Checking if a breast lump is a fluid-filled breast cyst (usually not cancerous) or a solid mass (which may require further testing).
    • Investigating a focal area in the breast that appeared abnormal on a mammogram.
    • Examining a pregnant woman's breasts in conjunction with physical exam.
    Mar 30, 2021

    What is the use of ultrasound in breast screening? ›

    A breast ultrasound is most often done to find out if a problem found by a mammogram or physical exam of the breast may be a cyst filled with fluid or a solid tumor. Breast ultrasound is not usually done to screen for breast cancer. This is because it may miss some early signs of cancer.

    Can ultrasound be used for breast cancer screening? ›

    Ultrasound is a particularly useful diagnostic modality in dense breast tissue, often detecting breast cancers obscured on mammography. Furthermore, if biopsy is required, ultrasound is the ideal imaging tool to guide subsequent procedures, further enhancing its utility in breast cancer diagnosis.

    Had mammogram called back for ultrasound? ›

    “When the radiologist interpreted that original screening mammogram, they saw either a change from the previous mammogram or they saw something new, and they want to take a closer look,” Susan said. “That results in the patient getting called back for additional views and sometimes an ultrasound.”

    What are the 4 main types of ultrasound scanning techniques? ›

    Types of Ultrasound
    • Endoscopic ultrasound.
    • Doppler ultrasound.
    • Color Doppler.
    • Duplex ultrasound.
    • Triplex ultrasound (color-flow imaging)
    • Transvaginal ultrasound.

    Why is a breast ultrasound better than a mammogram? ›

    Although ultrasonography, it is more sensitive than mammography in detecting lesions in women with dense breast tissue (7,10,12,13,16,17,18). In young women and women with dense breasts, ultrasound appears superior to mammography.

    What are the current screening methods for breast cancer? ›

    Mammography is the most common screening test for breast cancer. Magnetic resonance imaging (MRI) may be used to screen women who have a high risk of breast cancer. Whether a woman should be screened for breast cancer and the screening test to use depends on certain factors.

    Should I get ultrasound instead of mammogram? ›
