Can the radiologist recognize Helicobacter pylori gastritis?

To evaluate radiologic findings of Helicobacter pylori (H. pylori) in the upper gastrointestinal (UGI) tract, we retrospectively reviewed consecutive records of 676 symptomatic adults with gastric biopsies (224 positive) and 150 symptomatic adults with rapid urease tests (57 positive). All the UGI series of patients with positive biopsies or urease tests for H.

Limitations in distinguishing malignant from benign lesions of the breast by systematic review of mammograms.

Our objective was to assess whether or not a systematic review of mammographic descriptors would result in improved classifications of nonpalpable lesions of the breast and reductions of biopsies for benign conditions. The prelocalization mammograms of 200 consecutive patients who had 231 biopsies were reviewed in random order by four radiologists experienced in mammography. Each reader assessed the presence of 32 specific descriptors regarding masses and calcifications.

Complications of percutaneous nephrolithotomy.

Percutaneous nephrolithotomy: analysis of 500 consecutive cases.

The first 500 patients who underwent percutaneous stone removal at our hospital and who have been evaluated for at least 8 months were reviewed. Comparison of the first 100 patients with the entire series showed a sharp improvement in the success rate as the radiologic and urologic team gained experience. The success rate for simple pelvicaliceal stones was 98% in the entire series (vs.

Percutaneous extraction of renal stones: experience in 100 patients.

Recent developments in technology and instrumentation have made it possible to remove most kidney stones and many ureteral stones percutaneously. The first 100 cases at this institution were reviewed in which grasping, ultrasonic lithotripsy, basketing, and irrigation were used. In all cases, the follow-up was at least 1 year.
