The velocity of blood flow is minimum in
WebObjective: This study was undertaken to determine whether is there a difference in the middle cerebral artery peak systolic velocity (MCA PSV) between active and resting behavioral states in healthy fetuses aged 30 to 32 weeks. Methods: MCA blood flow was measured by pulsed Doppler sonography 3 times during each fetal behavioral state … WebA velocity-encoding phase subtraction technique was used to measure the velocity and flow rate of fluid flow in a phantom and blood flow in volunteers. METHODS. In a model, the authors measured constant flow velocities from 0.1 to 270.0 cm/second with an accuracy (95% confidence intervals) of ±12.5 cm/second.
