A Revolutionary Saturation Pulse with a High Flip Angle on 7 T Time-of-Flight Magnetic Resonance Angiography

On 7 T time-of-flight magnetic resonance angiography (7T TOF-MRA), this study aimed to apply minimum-time variable-rate selective excitation (MinVER) to a presaturation pulse (PSP) with a high flip angle to achieve a superior vessel-to-tissue contrast (VTCR), short acquisition time, and minor off-resonance effect. The performance of an adjusted PSP modified by employing the 90° flip…
