WebFast low angle shot (FLASH) is the most commonly used gradient spoiled gradient-echo MRI-sequence in abdominal imaging. FLASH uses radio frequency excitation pulses with a low flip angle (less than 90 degrees) and subsequent reading gradient reversal for producing a gradient echo signal. The small flip angle pulses create equilibrium of ... WebPrinciples, techniques, and applications of T2*-based MR imaging and its special applications. Radiographics 2009; 29:1433-1449.
