Contrast Enhancement in TOF cerebral angiography at 7 T using Saturation and MT pulses under SAR constraints: impact of VERSE and sparse pulses
Cerebral 3D time of flight (TOF) angiography significantly benefits from ultra high fields, mainly due to higher SNR and to longer T(1) relaxation time of static brain tissues, however, SAR significantly increases with B(0). Thus, additional RF pulses commonly used at lower field strengths to improv...
