ABSTRACT
The assessment of portal vein patency in patients selected as candidates for orthotopic liver transplantation should be accomplished noninvasively and with great accuracy. Magnetic resonance angiography (MRA) is a new technique that is completely noninvasive and is capable of graphically assessing portal vein anatomy and blood flow. In an attempt to establish the accuracy of portal venous MRA, 74 patients with established cirrhosis underwent abdominal MRA prior to liver transplantation. MRA findings were correlated with surgical findings at the time of transplantation in all patients, and were shown to be extremely accurate. The three-dimensional images generated by MRA and computer postprocessing allowed for correct identification of portal venous anatomy in all of the patients examined. We conclude that MRA is an extremely useful method of determining portal venous anatomy in potential liver transplant patients, and potentially offers greater definition and clarify compared with other non-invasive methods.
