PURPOSE To evaluate the clinical utility of dynamic gadolinium-enhanced magnetic resonance (MR) imaging of the breast with commercially available techniques in patients scheduled for excisional biopsy. MATERIALS AND METHODS A total of 91 breast abnormalities, 70 benign and 21 malignant, were evaluated. Thin-section three-dimensional gradient-echo images(More)
Most fungal infections of the urinary tract involve the drainage structures rather than the kidney parenchyma. They usually occur in patients with diabetes or other chronic debilitating diseases and in the presence of urinary stasis. Conglomeration of fibrillar hyphae results in fungal balls which produce nonopaque filling defects in the renal pelvis,(More)
Technical factors and diagnostic criteria that permit discrimination among diseases of the renal sinus are described. Because the size of the collecting system changes with the state of hydration, a standard approach permits optimal comparison of examinations performed on different occasions. A fluid challenge is indicated if relative or partial obstruction(More)
A prospective evaluation of computed tomography and ultrasound was performed on 24 consecutive patients with suspected pelvic masses. Of the 24 patients, 22 had subsequent surgical identification of abnormalities; two were considered normal on clinical follow-up. Ultrasound provided important clinical information in 17 of 24 patients; CT in 15 of 24(More)
Computed body tomography has become useful in the diagnosis of pancreatic disease. Pancreatitis frequently results in lateral and posterior extension of inflammatory tissue into the pararenal fat planes, which can be visualized by CT. In our series it was associated with clinically diagnosed pancreatitis. Of 100 cases studied for abdominal pathology where(More)
Does a normal leg phlebogram exclude deep venous thrombosis (DVT)? Is it safe not to anticoagulate patients with suspected DVT and a normal phlebogram? To answer these questions a retrospective study was undertaken of 71 outpatients with clinically suspected DVT and a normal phlebogram. Patients were followed for 5 months on the average; data were obtained(More)
The mammographic features of hidradenitis suppurativa axillaris, a common clinical entity, are described for the first time in this report. Lucent axillary masses with a small central density appear to be a pathognomonic radiographic finding. Other entities seen on mammography such as lipomas, lucent galactoceles, traumatic oil cysts, axillary hibernomas(More)
