Diffusion-Weighted MRI often suffers from signal attenuation due to long TE, sensitivity to physiological motion, and dephasing due to concomitant gradients (CGs). These challenges complicate image interpretation and may introduce bias in quantitative diffusion measurements. Motion moment-nulled diffusion-weighting gradients have been proposed to compensate motion, however, they frequently result in high TE and suffer from CG effects.

The LPI has contributed with 3 chapters to the new book Handbook of Speckle Filtering and Tracking in Cardiovascular Ultrasound Imaging and Video, published by the IET (Institution of Enigineering and Technology), edited by Christos P. Loizou, Constantinos S. Pattichis and Jan D’ hooge. Authors from the lab have added their expertise in Speckle Tracking and filtering.
A novel curl-based cardiac rotation measurement but from tensorial magnitudes devised to cardiomyopathy discrimination entitled "Vortical Features for Myocardial Rotation Assessment in Hypertrophic Cardiomyopathy using Cardiac Tagged Magnetic Resonance" has been recently published in the international journal Medical Image Analysis.
