Interobserver agreement with the new BI-RADS terminology is good and validates the US lexicon. Subcategories 4a, 4b, and 4c are useful in predicting the likelihood of malignancy.

To assess vein compressibility as a simple ultrasound (US) technique to determine the presence of venous thrombi, 51 patients undergoing contrast material venography of the lower extremity because of a clinical suspicion of deep venous thrombosis (DVT) also underwent high-resolution US evaluation of the veins. DVT was diagnosed on 28 venograms. In 25 patients US studies demonstrated non-compressibility of the veins, indicating the presence of clot. In 23 patients with normal venograms, US examinations demonstrated total compressibility of the veins, indicating the absence of DVT. Clots below the knee were not depicted by US. In this study US had a sensitivity of 89% and a specificity of 100%.

ObjectiveThe suggestion that breast cancer management is compromised in elderly patients had prompted our review of the results of policies regarding screening and early detection of breast cancer and the adequacy of primary treatment in older women (.65 ResultsThe frequency of mammographic screening for all averaged 40% in 1987, 52% in 1987, and 63% in 1995. In the 65-year-old and older patients, the frequency of screening was 34% in 1987, 45% in 1989, and 48% in 1995, whereas in the 40-to 49-year-old age group, the frequency of mammography was 47% in 1987, 61 % in 1989, and 74% in 1995 579
