IMAGING OF RENAL-TRANSPLANT - RADIOLOGICA L TECHNIQUES

Ultrasound examination with morphological sonography and color flow im aging is now considered as the main technique for the follow-up of ren al transplants. Morphology of the graft, and quality of perfusion can be assessed non invasively with this technique. Indications of IV pyel ography decreased considerably in many centers. CT can help in caracte rizing intra-abdominal collections.
