The aim of this work is to develop a T2W flip angle modulation SSFSE protocol. In breast MRI, FSE images are frequently utilised to acquire T2W images. SSFSE represents an ultrafast sequence where efficiencies in scan time could be made, however, SSFSE images are associated with blurring. Refocusing flip angle modulation has recently been utilised with SSFSE, benefits include, faster acquisitions and improved sharpness by limiting T2 decay. In this work T2W fat nulled SSFSE images were acquired in 70 seconds and provide radiologists with the same T2 information available in longer FSE based sequences.
