The purpose of this study was to evaluate the repeatability of 4D PC flow measurements in both arteries and veins of the abdominal circulation. 10 subjects, 3 patients with portal hypertension and 7 controls were included in the study. Excellent correlation and low percent difference between repeated measurements within the same day for both arterial and venous circulation demonstrates the repeatability of radial 4D flow MRI for quantifying blood flow in the abdominal circulation. Similarly comparison of day-to-day variation show that radial 4D flow MRI is repeatable for assessing mesenteric hemodynamics in controlled fasting states.
