Unenhanced MR angiography with spatial labeling with
multiple inversion pulses (SLEEK) is a reliable method for depicting portal
vein system in patients with liver transplantation compared with computed
tomographic portography (CTP) results. In a study of 20 patients who underwent liver
transplantation, we found that there was excellent correlation between SLEEK and CTP in
presenting the diameter of portal vein. Unenhanced MRA using SLEEK is relatively inexpensive and
is not associated with renal complications. It can be as a good choice for
screening portal vein system in patients with liver transplantation, especially
in patients with renal insufficiency.
