METHODS AND APPARATUS FOR REDUCING SCAN TIME OF PHASE CONTRAST MRI

摘要

A method and apparatus for reducing scan time, eddy currents and image factors in dynamic magnetic resonance (MR) imaging associated with at least a portion a k-space. The method includes scanning at least a portion of the k-space with an Echo-Planar Imaging (EPI) pulse sequence technique, acquiring a randomly under-sampled k-space; and reconstructing the under-sampled k-space utilizing a constrained reconstruction technique. A dynamic image is constructed of the at least a portion of the k-space based on EPI and the randomly undersampled k-space techniques to each segment of the EPI pulse sequence technique.
