Abstract

A dual-echo sequence technique provided herein empowers simultaneous acquisition of both TOF MRA and BOLD MRV in a single MR acquisition. By this approach, an echo-specific K-space ordering scheme permits the adjustment of the scan parameters that are compatible for each of the MRA and MRV. The image quality in the MRA and MRV acquired by this compatible dual-echo arteriovenography (CODEA) technique is comparable to that for conventional, single-echo MRA and MRV. When the technique is integrated with MOTSA, seamless vascular connectivity is achieved in both MRA and MRV over a large area of brain anatomy. The technique will facilitate routine clinical acquisition and application of dual-echo MRA and MRV, as both MRA and MRV can be acquired with minimal impact on the image quality and without adversely affecting the scan throughput.
