Unenhanced T2‐weighted fast spin‐echo images obtained in a 65‐year‐old woman with severe cirrhosis showed an area of high signal intensity occupying the left second‐order portal vein branch, suggesting portal vein thrombosis in cirrhosis. Doppler sonography, which revealed virtually no blood flow in the vessel, also supported the diagnosis. Gadolinium‐enhanced MRI subsequently revealed the patency of the vessel. The extremely slow portal venous flow was considered to be the cause of false‐positive findings with unenhanced MRI and sonography. J. Magn. Reson. Imaging 2002;15:199–202. © 2002 Wiley‐Liss, Inc.
