The usefulness of nuclear magnetic resonance (NMR) images in the evaluation of spinal disorders below the craniocervical junction was studied. Six normal subjects and 41 patients with various spinal abnormalities were examined. NMR proved capable of

In an effort to improve on our diagnostic yield from percutaneous transthoracic biopsy, we used 14-gauge cutting needles in 56 selected patients. These biopsies were pre- [9,[13][14][15][16][17][18].In an attempt to improve these previous results, we reintroduced the large cutting needle for the biopsy of carefully selected chest lesions. This report reviews our experience with 56 chest biopsies performed with a lange-bore cutting needle during the last 6 years. In 42 patients, results from their cutting-needle biopsies were compared with those from their aspiration biopsies. This study establishes the diagnostic advantages of lange-bone cutting-needle biopsies and shows their safety, when they are used according to specified methods in a select group of patients. From 1981From to mid-1987 Methods

Ten normal volunteers and 45 patients with breast abnormalities were examined with magnetic resonance (MR), utilizing a 0.3-tesla superconducting magnet. In all patients, MR detected an abnormality that corresponded to the area of pathology seen on either a mammogram or computed tomographic (CT) scan. An appreciable advantage of MR over mammography was observed in patients with cysts and in those with areas of asymmetric dysplastic breast tissue. Abnormalities on MR images appeared as areas of low signal intensity relative to adjacent normal ductal and fatty tissue. The configuration of a lesion on MR permitted distinction between a benign and a malignant process.
