Imagerie diagnostique du rein transplanté et des complications de la greffe rénale

Imaging is indicated prior to transplantation in order to evaluate the graft and assess its vascular anatomy in potential living donors. After the transplantation, the main role of imaging is to detect vascular and urological complications, which do not require biopsy and can lead to reconstructive surgery or percutaneous management. In most cases, the first line imaging modality is the colour doppler ultrasonography. Compared to iodinated contrast-enhanced CT, contrast-enhanced MRI provides accurate, noninvasive and nonnephrotoxic evaluation of the arterial pedicle and perfusion disorders.
