We have implemented and demonstrated markedly improved imaging of both time-of-flight (TOF) MR angiogram (MRA) and blood oxygenation level-dependent (BOLD) MR venogram (MRV) at 7T that were acquired simultaneously using a newly developed compatible dual-echo arteriovenography (CODEA) technique, in comparison with the CODEA MRA/MRV at 3T. Preliminary results indicate imaging at the higher-field allows improved visualization of small vessels in MRA and MRV due to greatly increased signal-to-noise ratio (SNR) and susceptibility contrast.
