BACKGROUND AND PURPOSE Vascular dementia (VD) has been an ill-defined term thus far. Recently detailed criteria for the diagnosis of VD have been proposed (Alzheimer's Disease Diagnostic and Treatment Centers [ADDTC], 1992; Diagnostic and Statistical Manual of Mental Disorders, 4th edition [DSM-IV], 1994; International Classification of Diseases, 10th(More)
We present three cases of GC, one belonging to the brainstem, and two belonging to the hemisphere type. Two cases were investigated by MRI. Tumour infiltration, while yielding only vague CT findings, was well demonstrated in MR studies where extensive hyperintense lesions were found in T2- and proton density images. In patients studied by MR these were(More)
Bone density measurements were performed on 51 patients with suspected osteoporosis. We used DE-QCT and DEXA. The methods were compared with regard to deviation from normal. In 29 of the 51 patients there was more than half standard deviation and in 12 of the 51 cases there was more than a full standard deviation.
Results of 39 intravenous and intraarterial DSA studies of haemodialysis access fistula are presented. Advantages of DSA versus conventional fistulography and xeroangiography are discussed. Digital subtraction angiography represents an accurate, time-saving and low complication approach to the evaluation of failing dialysis access fistulas.
Three-dimensional reconstruction from CT was performed in pediatric patients after joint, facial, or spinal injury. Three-dimensional reconstruction proved particularly helpful in children with reduced post-trauma joint mobility. Free fragments, joint dislocations, and articulate surface defects were demonstrated. Here, as well as in facial and spinal(More)
Opacification of the gastrointestinal tract for CT scanning is usually achieved by oral administration of a diluted iodine solution or barium suspension. As high-density contrast agents often cause image degrading artifacts, we investigated the value of a paraffin-methylcellulose emulsion as an oral CT scanning agent. Diseases of the intestinum were clearly(More)
Diagnosis of ligament ruptures via the possibilities of conventional radiology is often insufficient. To verify CT efficiency, postmortem specimens were scanned in axial, coronal and sagittal planes and compared with anatomical findings of sections in identical planes. After the preliminary examinations we conducted a study on 32 patients. The examinations(More)
