摘要：
Whereas conventional MRA relies on enhanced blood signal from flow-induced magnitude and/or phase effects, gadolinium-enhanced MRA relies mainly on the enhanced blood signal caused by the reduced relaxation time T1. This has a large impact on the imaging technique used, as well as on the imaging volume orientation and the total scanning time. In general, gadolinium-enhanced MRA is faster, with fewer artifacts than MRA without contrast agents.
