To compare hand-held breast ultrasound (HHBUS) and automated breast ultrasound (ABUS) as screening tool for cancer.
A cross-sectional study in patients with mammographically dense breasts was conducted, and both HHBUS and ABUS were performed. Hand-held breast ultrasound was acquired by radiologists and ABUS by mammography technicians and analyzed by breast radiologists. We evaluated the Breast Imaging Reporting and
(BI-RADS) classification of the exam and of the lesion, as well as the amount of time required to perform and read each exam. The statistical analysis employed was measures of central tendency and dispersion, frequencies, Student t test, and a univariate logistic regression, through the odds ratio and its respective 95% confidence interval, and with p<0.05 considered of statistical significance.
Atotal of 440 patientswere evaluated. Regarding lesions,HHBUS detected 15 (7.7%) BI-RADS 2, 175 (89.3%) BI-RADS 3, and 6 (3%) BI-RADS 4, with 3 being confirmed by biopsy as invasive ductal carcinomas (IDCs), and 3 false-positives. Automated breast ultrasound identified 12 (12.9%) BI-RADS 2, 75 (80.7%) BI-RADS 3, and 6 (6.4%) BI-RADS 4, including 3 lesions detected by HHBUS and confirmed as IDCs, in addition to 1 invasive lobular carcinoma and 2 high-risk lesions not detected by HHBUS. The amount of time required for the radiologist to read the ABUS was statistically inferior compared with the time required to read the HHBUS (p<0.001). The overall concordance was 80.9%. A total of 219 lesions were detected, from those 70 lesions by both methods, 126 only by HHBUS (84.9% not suspicious by ABUS) and 23 only by ABUS.
Compared with HHBUS, ABUS allowed adequate sonographic study in supplemental screening for breast cancer in heterogeneously dense and extremely dense breasts.

SUMMARY Myiasis is defined as a parasitosis caused by the developing larvae of some species of flies that infest humans or animals. The authors present two cases of primary myiasis. They call attention to the characteristics observed in this pathology in the differential diagnosis of the inflammatory diseases in the breast.

PURPOSE: the technological improvements in image quality have increased the importance of ultrasound as an imaging method in the study of breast pathologies. The need for a standardized method for lesion characterization, description and reporting in image analysis motivated the development of a breast sonographic report classification system. METHODS: the classification grouped the breast sonographic images in five classes: I - normal; II - benign; III - indeterminate, IV - suspect, and V - highly suspect. The used morphologic ultrasound features were shape, border, contour, echogenicity, echotexture, sound transmission, orientation, and secondary signals. The gold standard test, in the study of 450 lesions, considered sonographic follow-up of the lesions for a period from 6 to 24 months and the histopathology of surgical cases. RESULTS: breast sonographic classification for the diagnosis of breast cancer showed a sensitivity of 90.2% (CI: 82.8-94.9%), a specificity of 96.2% (CI: 94.0-97.6%), a positive predictive value of 84.1% (CI: 76.0-89.9%), and a negative predictive value of 97.8% (CI: 95.9-98.9%), obtaining an accuracy of 95.1%. CONCLUSIONS: the adoption of a sonographic classification system results in the standardization and optimization of the reports. It also aids the comparison with clinical findings, histopathological tests and breast images, avoiding unnecessary procedures and therefore leading to more adequate therapeutical management.
