RATIONALE AND OBJECTIVES With the use of localized, water-suppressed in vivo 1H magnetic resonance spectroscopy (MRS), the proton metabolic alterations of white matter in patients with closed head injury (CHI) and healthy controls are evaluated, and metabolic alterations with Glasgow Outcome Scale (GOS) scores are compared. METHODS Patients with CHI (n =(More)
Posterior apophyseal ring fracture (PARF) of the lumbar spine is an uncommon injury thought usually to occur in adolescence. We analysed CT findings in 20 cases (19 patients), whose age ranged from 16 to 45 years (average 30 years). The PARF could be divided into two distinct groups on the basis of the shape and location of the fracture and the defect of(More)
PURPOSE To describe the MR characteristics that can distinguish idiopathic transverse myelitis from other intramedullary lesions. METHODS A total of 32 initial and follow-up MR studies in 17 patients with clinically proved transverse myelitis were reviewed retrospectively. The location, size, pattern, and segmental length of areas of hyperintensity were(More)
We evaluated the CT of intestinal obstruction due to adhesions in 20 postoperative patients, with emphasis on early detection of strangulation. Ten patients with surgically proven strangulated obstruction (strangulation group) were compared with another ten patients (nonstrangulation group) in whom seven improved with conservative management and three had(More)
RATIONALE AND OBJECTIVES To investigate postmortem metabolic and morphologic alterations in the dog brain thalamus and to contribute diagnostic aids in medicolegal science. METHODS A homogeneous group of 17 dogs was used for in vivo 1H magnetic resonance (MR) spectroscopy and electron microscopic studies, which were performed under intravenous and(More)
PURPOSE A prospective Phase II study of a novel maintenance biotherapy regimen after induction biochemotherapy was conducted in patients with metastatic melanoma in efforts to maintain responses and improve survival. EXPERIMENTAL DESIGN Thirty-three patients with poor prognosis metastatic melanoma who achieved a partial response (PR) or stable disease(More)
PURPOSE To evaluate the computed tomographic (CT) features of systemic lupus erythematosus (SLE) in patients with acute abdominal pain. Special emphasis was placed on the analysis of ischemic bowel disease. MATERIALS AND METHODS The authors retrospectively reviewed the images from 39 abdominal CT examinations performed in 33 patients with SLE and acute(More)
PURPOSE To determine the impact of stereotactic radiosurgery (SRS) on the clinical course, hormonal status, and follow-up CT/MRI scan of pituitary macroadenomas. METHODS AND MATERIALS From July 1988 to March 1996, 24 pituitary macroadenomas had been treated using 6 MV linear accelerator based SRS. They consisted of 11 (45.8%) prolactinomas, 2 (8.3%)(More)
PURPOSE To evaluate the computed tomographic (CT) features of xanthogranulomatous cholecystitis (XGC) and to distinguish it from gallbladder carcinoma. MATERIALS AND METHODS Retrospective analysis was performed in 11 patients with XGC and 17 patients with gallbladder carcinoma in which the wall was thickened. The following CT features were analyzed:(More)
RATIONALE AND OBJECTIVES The authors investigate: (1) whether there is a lateral effect of hydrogen (1H) magnetic resonance (MR) spectroscopy observable metabolite ratios between the right and the left prefrontal lobe in chronic schizophrenia; (2) whether there is a change of proton metabolite ratios in chronic schizophrenia after neuroleptic treatment; (3)(More)
