title: Noninvasive imaging of liver transplant complications.
abstract: Noninvasive cross-sectional imaging modalities include ultrasound, computerized tomography, and magnetic resonance imaging. Each of these imaging methods has unique applications for vascular imaging. This article will review the technical parameters of each of the 3 modalities, including specialized vascular techniques. The main vascular transplant complications will then be discussed with respect to the diagnostic criteria and applicability of each of the relevant modalities. Transplant complications including hepatic artery stenosis and thrombosis, stenosis and thrombosis of the portal vein or inferior vena cava, and hepatic vein stenosis will be discussed. Sequelae of hepatic artery stenosis including biliary necrosis will also be reviewed briefly.
