3D TOF MRA of the intracranial arteries: effects of increasing magnetic field to 4.7T

Wilman A, Eissa A

Utilizing 4.7T magnets in 3D TOF MRA has the expected benefits of higher SNR and more background signal suppression. It also has concerns with respect to RF focusing. The study was done on 15 healthy volunteers with flow compensated 3D TOF MRA sequence. Theoritical considerations were also addressed.
