Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses
Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2568-2579, May 2026.ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans
Advanced Science, Volume 13, Issue 19, 2 April 2026.Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...
