PURPOSE: To evaluate contrast-enhanced MR angiography for the distinction between perigastric and submucosal fundal varices.
MATERIALS AND METHODS: Nineteen consecutive patients with clinically suspected fundal varices underwent contrast-enhanced MR angiography and endoscopic ultrasound (EUS) within one week. Diagnostic confidence for the detection of perigastric and submucosal fundal varices was compared between MR angiography (two radiologists) and EUS (one gastroenterologist), and the agreement of size and location was evaluated.
RESULTS: Both MR angiography and EUS detected perigastric varices in all 19 patients and submucosal fundal varices in 14 of the 19 patients. The interobserver reliability of MR angiography was good for measuring the variceal diameter (kappa = 0.76) and excellent for localizing the varices (kappa = 1.0). EUS and MR angiography agreed in 12 of 14 patients (86 %) in determining variceal diameter and location.
CONCLUSIONS: Contrast-enhanced MR angiography is comparable to endoscopic ultrasound in the detection and characterization of gastric fundal varices.
