**7.3. Image diagnosis**

In the post-transplant period, radiological examinations should be perfomed to evaluate graft perfusion and exclude surgical complications, such as collections or thrombosis. Most centers rely on ultrasound as their preferred method, since it is easy to use, nontoxic, and may be pefomed as often as needed. When available, computerized tomography may provide further information, such as contrast-enhanced evaluation of arterial perfusion and venous drainage, as well as exclude possible hemorrhages. Herein, we describe in detail advantages of each option.
