Percutaneous portal venography.
Portal venography by percutaneous injection of the spleen was first performed in dogs (Abeatici and Campi, 195I) and the method was later successfully applied in man (Leger, 1951; Boulvin et al., 195I; Campi and Abeatici, I952). In the last few years the method has been routinely used at a number of centres in the British Isles. Atkinson, Barnett, Sherlock and Steiner (I955) have described abou...
متن کاملCO(2) wedged hepatic venography in the evaluation of portal hypertension.
BACKGROUND/AIMS/METHODS During hepatic vein catheterisation, in addition to measurement of hepatic venous pressure gradient (HVPG), iodine wedged retrograde portography can be easily obtained. However, it rarely allows correct visualisation of the portal vein. Recently, CO(2) has been suggested to allow better angiographic demonstration of the portal vein than iodine. In this study we investiga...

At a dose of 45 mg/day the same extrapyramidal syndrome re-emerged and was completely responsive to trihexyphenidyl 2 mg by mouth three times daily. After haloperidol dosage was increased to ...
متن کاملDual Energy CT (DECT) Monochromatic Imaging: Added Value of Adaptive Statistical Iterative Reconstructions (ASIR) in Portal Venography
OBJECTIVE To investigate the effect of the adaptive statistical iterative reconstructions (ASIR) on image quality in portal venography by dual energy CT (DECT) imaging. MATERIALS AND METHODS DECT scans of 45 cirrhotic patients obtained in the portal venous phase were analyzed. Monochromatic images at 70keV were reconstructed with the following 4 ASIR percentages: 0%, 30%, 50%, and 70%. The im...
متن کاملMR venography of multiple sclerosis.
BACKGROUND AND PURPOSE The distribution of multiple sclerosis (MS) lesions in the brain follows a specific pattern, with most lesions in the periventricular regions and in the deep white matter; histopathologic studies have shown a perivenous distribution. The aim of this study was to illustrate these distribution patterns in vivo using high-resolution MR venography. METHODS Seventeen MS pati...
