PURPOSE To determine the ability of magnetic resonance (MR) arthrography to depict the anatomic reestablishment of the capsulolabral complex after suture-anchor Bankart repair. MATERIALS AND METHODS Thirty patients (25 men, five women; mean age, 28 years) who had undergone suture-anchor Bankart repair of one shoulder underwent MR arthrography before(More)
The occurrence of tumor in the small intestine is relatively rare. It has been demonstrated that lipoma of the ileum is a cause of intussusception. We report a 59-year-old man admitted to our hospital for lower abdominal pain. Diagnosis of intussusception was made by abdominal x-ray and ultrasonography. Enema contrast studies revealed ileocolic(More)
AIMS The aims of this study were to assess the efficacy and toxicity of concurrent chemoradiotherapy with divided schedule of cisplatin and vinorelbine in patients with locally advanced non-small-cell lung cancer (NSCLC). METHODS Patients with previously untreated, unresectable, and stage IIIA or IIIB NSCLC were eligible if they had a performance status(More)
Magnetic resonance imaging (MRI) of the breast has become important not only for assessing the extent of breast cancer for breast-conserving surgery but also for the evaluation and diagnosis of other benign and malignant pathologies. We radiologists therefore need to know the appropriate indications for performing breast MRI and understand the MRI features(More)
The effect of driving waveform, reflective vs backlit transmissive mode, and contrast polarity, on the legibility of a multiplexed twisted nematic (TN) LCD were investigated. The backlit transmissive mode with a white display pattern on dark background (W/B contrast) resulted in superior display legibility, while the reflective mode TN LCD with a dark(More)
Between December 1968 and December 1983, the authors treated 30 patients requiring gastrectomy for carcinoma of the postoperative stomach. The patients were divided into two groups: 13 patients were operated on for primary carcinoma lesions (Group A) and 17 patients for benign lesions (Group B). Respective areas of carcinoma development and length of time(More)
We have treated head and neck carcinoma by concurrent chemoradiotherapy combined with 5-fluorouracil (5-FU) and cisplatin (CDDP). However,this chemoradiotherapy could not show an enormous effect in the advanced carcinoma of Stage III and IV. Therefore,we changed the contents of the chemotherapy, i.e., we replaced 5-FU, one of the agents with time(More)
The purpose of this study was to determine whether a distinction could be made between benign and malignant urinary obstructions in moderately T(2)-weighted images obtained with the single-shot fast spin-echo technique. Forty-four lesions in 39 patients with urinary obstruction were evaluated with the single-shot fast spin-echo (SSFSE) technique with an(More)
