PURPOSE To determine the usefulness of five magnetic resonance (MR) signs of repeat tears of the postoperative meniscus. MATERIALS AND METHODS Fat-saturated proton-density-weighted and T2-weighted MR images in 20 patients who had undergone at least two knee surgeries were reviewed. Second-look arthroscopic confirmation of meniscal status was available in(More)
PURPOSE To demonstrate the signal characteristics of subcutaneous rheumatoid nodules in correlation to their histopathologic features. METHOD The magnetic resonance imaging (MRI) features of biopsy proven subcutaneous rheumatoid nodules are described in five patients with rheumatoid arthritis established by classic criteria. RESULTS Two morphologic(More)
PURPOSE The purpose of this study is to determine if focused CT examinations of the pelvis, utilizing fixed oral dosage of diatrizoate contrast media, improve overall reader confidence in visualization of the appendix. MATERIALS AND METHODS Five hundred and twenty-five patients referred for, rule out appendicitis, evaluations underwent focused CT(More)
Descending necrotizing mediastinitis (DNM) is a relatively rare condition caused by downward spread of neck infections into the mediastinum. This infection previously had a much worse prognosis. In recent years, prompt computer topography (CT) diagnosis has been recommended. CT scan provides the earliest means of detecting DNM for optimal management and(More)
Automated breast ultrasound (ABUS)was performed in 3418 asymptomatic women with mammographically dense breasts. The addition of ABUS to mammography in women with greater than 50% breast density resulted in the detection of 12.3 per 1,000 breast cancers, compared to 4.6 per 1,000 by mammography alone. The mean tumor size was 14.3 mm and overall attributable(More)
Grammatical and syntactic rules designed for the production of "smooth" automatic translations between human languages will be called translation algorithms. Because of the rigid constraints imposed by automatic machines, the formulation of translation algorithms involves unprecedented problems of a linguistic nature. Much of the existing literature in the(More)
The purpose of this study was to optimize detection of the normal appendix in the clinical exclusion of acute nonperforated appendicitis using an improved and rapid method of bowel opacification in conjunction with the CT examination. A prospective evaluation of 100 consecutive patients, ranging from 13 to 50 years in age, was performed over a 4-month(More)
