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.
