OBJECTIVE: To compare the performance of synthetic mammography (SM) and digital mammography (DM) with digital breast tomosynthesis (DBT) or alone for the evaluation of microcalcifications. METHODS: This retrospective study includes 198 mammography cases, all with DM, SM, and DBT images, from January to October 2013. Three radiologists interpreted images and recorded the presence of microcalcifications and their conspicuity scores and final BI-RADS categories (1, 2, 3, 4a, 4b, 4c, 5)...

In the current study, we sought to evaluate the diagnostic efficacies of conventional ultrasound (US), contrast-enhanced US (CEUS), combined US and CEUS and magnetic resonance imaging (MRI) in detecting focal solid breast lesions. Totally 117 patients with 120 BI-RADS category 4A-5 breast lesions were evaluated by conventional US and CEUS, and MRI, respectively. SonoVue was used as contrast agent in CEUS and injected as an intravenous bolus; nodule scan was performed 4 minutes after bolus injection. A specific sonographic quantification software was used to obtain color-coded maps of perfusion parameters for the investigated lesion, namely the time-intensity curve...

Background Elastography has been introduced as an additional diagnostic tool to ultrasonography (US) which helps clinicians decide whether or not to perform biopsy on US-detected lesions. Purpose To evaluate the role of strain elastography in downgrading Breast Imaging Reporting and Data System (BI-RADS) category 4a breast lesions according to personal risk factors for breast cancer in asymptomatic women. Material and Methods Strain elastography features of a total of 255 asymptomatic category 4a lesions were classified as soft and not soft (intermediate and hard)...

A 34-year-old primigravid woman presents for a routine prenatal visit at 18 weeks of gestation with a breast lump. On examination, she has a painless, firm breast mass measuring 3-4 cm in diameter with overlying skin dimpling. A diagnostic mammogram shows findings suspicious for malignancy (Breast Imaging Reporting and Data System [BI-RADS] 4), and core biopsy demonstrates an invasive ductal carcinoma with both estrogen and progesterone receptor-positive staining. The patient asks: "How will this affect my pregnancy, and what is the safest course of action?"...

Introduction: Most of the currently available automated breast ultrasound systems require patients to be in the supine position. Previous data, however, show a high recall rate with this method due to artifacts. The novel automated breast ultrasound scanner SOFIA scans the breast with the patient in a prone position, resulting in even compression of breast tissue. We present our initial results with this examination method. Material and Methods: 63 patients were analyzed using a handheld B-mode ultrasound...

Objective: The automated breast ultrasound system (ABUS) is a potential method for breast cancer detection; however, its diagnostic performance remains unclear. We conducted a hospital-based multicenter diagnostic study to evaluate the clinical performance of the ABUS for breast cancer detection by comparing it to handheld ultrasound (HHUS) and mammography (MG). Methods: Eligible participants underwent HHUS and ABUS testing; women aged 40-69 years additionally underwent MG...

PURPOSE: To evaluate the efficacy of added shear wave elastography (SWE) in breast screening for women with results inconsistent between mammography and conventional ultrasounds (US). MATERIALS AND METHODS: The study consisted of 282 pathologically proven breast lesions. The cancer probability from screening by mammography and conventional US were scored using Breast Imaging Reporting and Data System (BI-RADS). Elastography was used to re-evaluate inconsistent conventional US and mammography results...

Objective: To investigate the value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of BI-RADS 4 breast masses. Methods: A total of 72 patients were collected from the First Hospital of Shanxi Medical University from January 2016 to December 2017.79 breast masses were confirmed by biopsy or surgical pathology.All the masses were classified by BI-RADS according to conventional ultrasound and CEUS was performed in parallel.Based on the results of the CEUS predictive model, the benign and malignant features of the breast BI-RADS type 4 tumors were re-determined: (1) conventional ultrasound BI-RADS classification+ CEUS predictive model: both of them were malignant when malignant; (2) re-adjusting BI-RADS classification by CEUS predictive model: if the malignant CEUS predictive model, upgrade a class, if the benign CEUS predictive model, downgrade a class...

OBJECTIVE: The purpose of this study was to compare diagnostic accuracy and interpretation time of screening automated breast ultrasound (ABUS) for women with dense breast tissue without and with use of a recently U.S. Food and Drug Administration-approved computer-aided detection (CAD) system for concurrent read. MATERIALS AND METHODS: In a retrospective observer performance study, 18 radiologists interpreted a cancer-enriched set (i.e., cancer prevalence higher than in the original screening cohort) of 185 screening ABUS studies (52 with and 133 without breast cancer)...

Objective: To evaluate suspicious amorphous calcifications diagnosed on full-field digital mammography (FFDM) and establish correlations with histopathology findings. Materials and Methods: This was a retrospective study of 78 suspicious amorphous calcifications (all classified as BI-RADS® 4) detected on FFDM. Vacuum-assisted breast biopsy (VABB) was performed. The histopathological classification of VABB core samples was as follows: pB2 (benign); pB3 (uncertain malignant potential); pB4 (suspicion of malignancy); and pB5 (malignant)...
