The accuracy of CT diagnosis of increased fat deposition in the liver was assessed in 11 alcoholic patients with suspected fatty liver. Single-energy CT attenuation values were compared with histological assessment of fatty liver and chemical analysis of liver triglyceride concentrations, obtained from liver biopsy specimens. Measured attenuation values… (More)
We analyzed the serum concentrations of lipids and lipoproteins and the prevalence of other risk factors in a case-control study of 304 consecutive Chinese patients with acute stroke (classified as cerebral infarction, lacunar infarction, or intracerebral hemorrhage) and 304 age- and sex-matched controls. For all strokes we identified the following risk… (More)
From 1965 to 1972, 19 patients with the Budd-Chiari syndrome were investigated. An underlying diagnosis was made in 10 cases, polycythemia rubra vera being the commonest etiology. Percutaneous liver biopsy confirmed the diagnosis in 18 patients, and in 14 the site of hepatic vein obstruction was defined or its presence suggested by hepatic venography.… (More)
By comparison with age-matched controls in employment, 17 institutionalised schizophrenic patients were shown by computerised axial tomography of the brain to have increased cerebral ventricular size. Within the group of schizophrenic patients increased ventricular size was highly significantly related to indices of cognitive impairment.
The anatomy and radiology of the areae gastricae were studied in human and pig specimens and it was shown that the double contrast barium meal demonstrates a true picture of the undulating gastric mucosa, which is distinctive in appearance in the antrum body and fundus of the pig stomach. The importance of the type of barium used and the thickness of… (More)
Mean lung attenuation has been measured on computed tomography (CT) sections through lung bases of 17 patients with no evidence of respiratory disease. Sections were obtained in inspiration and at neutral respiration together with spirometric measurement of lung volume changes. The normal range for mean attenuation including all phases of respiration is… (More)
Attention is drawn to the variation in the computed tomography (CT) attenuation value of water with temperature. A difference of 5 to 6 Hounsfield units (1,000 scale) between typical room and body temperatures can be predicted as a consequence of the change in the density of water and was confirmed experimentally. This difference may be of significance in… (More)
