Fig. 11From: Role of imaging in the evaluation of vascular complications after liver transplantationPortal vein stenosis. Portal vein stenosis is demonstrated on CT, both on axial images (a) and in multiplanar reconstructions (b). After stent placement, a control ultrasound is performed (c). It shows normalisation of the portal flow. Control MRI (d) shows metallic artefact of the stent. Normal contrast enhancement is seen both proximal and distal to the stentBack to article page
