摘要：

A now phantom was used to study MR volume now measurements for monophasic and triphasic waveforms over the now range expected in peripheral arteries at rest and with exercise (2-24 mL/sec, n = 50). The improvement in accuracy with phase-correction image processing to eliminate errors caused by eddy currents was measured, Volume now estimates with Doppler sonography were also measured, MR volume now measurements correlated with volume collection with r = .996 and mean error = 4.6%, Phase-correction processing decreased mean error from 12.6% to 4.6% (P < .001, paired t-test), Doppler sonography had a higher mean error of 10.3% (P < .001, unpaired t-test). Cine phase-contrast MR imaging provides accurate estimates of volume blood now for waveforms and now ranges expected in peripheral arteries.
