Dysplastic nodules in liver cirrhosis: evaluation of hemodynamics with CT during arterial portography and CT hepatic arteriography.

abstract：:To assess the potential role of ultrasound (US) in evaluating transjugularly inserted intrahepatic portosystemic shunts, the authors performed sonographic, including duplex and color Doppler, studies in 23 patients. Imaging was performed before, during the first week after, and 2-3 months after shunt placement. The pr...
