Role of 3d automated breast ultrasound as a future breast screening tool in addition to mammography

Background:Breast cancer is the most common malignant tumor in females, diagnosed in approximately 1.4 million people each year.Mammography is considered the gold standard for breast cancer screening yielding 30% reduction in breast cancer mortality among women.Automated Breast Ultrasound (ABUS)is a new technique that was developed to obtain an operator independent system. Aim of the study: evaluation of validity of ABUS in cancer breast detection in addition to Mammography. Subject and Methods: This prospective cross-sectional study was done at radiology department of Al Sheikh Zayed Aal Nahyan hospital and included 105 female patients, aged >18 years old, presented with breast complaint or screening, they were referred from general surgery Department of Al Sheikh Zayed Aal Nahyan Hospital. They were evaluated by mammography and ABUS individually. Each lesion was assigned an independent BIRADS score for each modality. diagnosis was confirmed by biopsy (56cases). Results:ABUS and Mammography showed fair substantial agreement regarding lesions classification (benign or malignant) with kappa (κ) 0.549. with diagnostic accuracy and sensitivity of ABUS were higher than that of mammography as for ABUS were 97.1% and 100% respectively, while for mammography were 83.8% and 67.4% respectively. Conclusions: From our results ABUS may serve as an effective new screening tool in addition to mammography.
