a) Pulse diagram for measuring arterial T1. Following an adiabatic 180° inversion pulse, a series TFE acquisitions are used to sample the inversion recovery curve with an interval that allows the blood magnetization to refresh in the imaging plane. THK=slice thickness; v=blood velocity. b) The survey image shows the B1 coverage of the whole upper torso when centered at clavicle. c) Time of flight angiographic scout image. The red box indicates the imaging slice chosen to the ICA. d) one representative image from the fast T1 protocol (TI=9850ms).
