The Breast Imaging Reporting and Data System (BI-RADS) initiative, instituted by the ACR, was begun in the late 1980s to address a lack of standardization and uniformity in mammography practice reporting. An important component of the BI-RADS initiative is the lexicon, a dictionary of descriptors of specific imaging features. The BI-RADS lexicon has always(More)
OBJECTIVE The purpose of this study was to compare the outcome of sonographically guided core biopsies performed with the 14-gauge automated gun with the outcome of those performed with the 11-gauge vacuum-assisted device. Outcome was defined in terms of missed tumors, the need (both immediate and delayed) for a second biopsy, histologic underestimation,(More)
PURPOSE To measure the effect of biopsy device, probe size, mammographic lesion type, lesion size, and number of samples obtained per lesion on the ductal carcinoma in situ (DCIS) underestimation rate. MATERIALS AND METHODS Nonpalpable breast lesions at 16 institutions received a histologic diagnosis of DCIS after 14-gauge automated large-core biopsy in(More)
Ventilation-perfusion scans were used in a prospective study to determine the prevalence of occult pulmonary embolus in proven deep venous thrombosis. Fifty-eight patients without symptoms of pulmonary embolism, but with venographically proven deep venous thrombosis, were subjected to chest radiographs, 99mTc macroaggregated-albumin perfusion scans, and(More)
The objective of this study was to evaluate the impact of tamoxifen treatment on amount of fibroglandular tissue (FGT), background parenchymal enhancement (BPE), and cysts on breast MRI. Retrospective search identified 96 women with breast cancer who had a breast MRI both before and during adjuvant tamoxifen therapy between 2002 and 2008. After exclusion of(More)
Screening for breast cancer with mammography has been shown to decrease mortality from breast cancer, and mammography is the mainstay of screening for clinically occult disease. Mammography, however, has well-recognized limitations, and recently, other imaging including ultrasound and magnetic resonance imaging have been used as adjunctive screening tools,(More)
This prospective study examined the influence of perceived susceptibility to breast cancer on nonadherence to recommended mammography screening guidelines. The study population included 1,229 African American and White women ages 40 to 79 years who obtained an index mammography screening examination at one of five urban hospitals in Connecticut between(More)
MR imaging is emerging as a valuable adjunct to mammography and ultrasound for the evaluation of the breast. Breast MR imaging has high sensitivity for the detection of breast cancer but suffers from a relatively low specificity. There is growing experience with this imaging modality as applied to breast diseases and more standardization in obtaining and(More)
PURPOSE To assess the accuracy of stereotactic core-needle biopsy (CNB) of nonpalpable breast lesions within the context of clinically important parameters of anticipated tissue-sampling error and concordance with mammographic findings. MATERIALS AND METHODS CNB was performed in 1,003 patients, with results validated at surgery or clinical and(More)
OBJECTIVE Despite relatively high mammography screening rates, there are reports of inadequate follow-up of abnormal results. Our objective was to identify factors associated with inadequate follow-up, and specifically, to determine if this outcome differed by race/ethnicity. METHODS We studied 176 subjects with abnormal or inconclusive mammograms(More)
