Biliary complications are the most common source of morbidity after liver transplantation as they may occur in up to 45%of patients(1).The review by Magro et al.(2)provides comprehensive insights on this topic and offers a cue for in-depth remarks form a radiological perspective regarding both diagnostic and interventional aspects.Ultrasound(US)-based techniques,including B-mode and color-Doppler,are the milestone of post-transplant follow-up.The assessment of graft vascularization is crucial since many biliary complications are supposed to be induced by arterial ischemia.To this regard,however,it must be emphasized that US imaging is hampered by a limited panoramic view,especially in difficult abdomens,therefore it is not possible to rely exclusively on this technique.
