Unenhanced MR angiography with spatial labeling with
multiple inversion pulses (SLEEK) is a reliable method
for depicting anatomy and complications from renal
vascular transplant compared with digital subtraction
angiography and intraoperative results. In a study of 75
patients who underwent renal transplantation, we found
that unenhanced MR angiography with SLEEK enabled
visualization of small branches within the transplant
renal parenchyma and subtle accessory renal arteries.
The method may show transplant renal veins while
suppressing the signal from the inflowing arterial vein.
SLEEK MR angiography is a promising alternative
technique for assessing renal vessels in patients with
