Fig. 8.

Nine-year-old with history of hemolytic uremic syndrome who has undergone right lower quadrant renal transplant. a Maximum intensity projection (MIP) reformat image from the arterial phase of the dynamic post-contrast sequence shows a patent artery supplying the right lower quadrant renal transplant (arrow). b Subsequent MIP image from the corticomedullary phase shows multifocal regions of parenchymal thinning and scarring (red arrows) with the most pronounced region of scarring in the lower pole medially (blue arrow). c MIP delayed post-contrast excretory phase image shows excretion of contrast into the renal transplant collecting system and ureter without dilation and with free passage of contrast into the bladder. The small native kidneys can also be seen. d MIP reformat of 3D T2-weighted fast spin-echo image shows no pelvocaliectasis with mild tortuosity of the ureter. The small native kidneys and ureters can also be seen
