Abstract

PURPOSE: To develop a method capable of effectively suppressing blood flow signals in arbitrary directions, thereby improving the black-blood contrast in head-neck vessel wall imaging (VWI). METHODS: The polarities of gradients in the conventional delay alternating with nutation for tailored excitation (DANTE) module were toggled at each TR, forming three linearly independent black-blood gradient…
