Prostate imaging at Ultra High Field suffers from SAR limitations and B1 inhomogeneity. This is especially effects Turbo Spin Echo for T2 weighted imaging, although this contrast holds significant clinical value. Steady-State Free Precession offers a T2/T1 contrast with lower flip angles and potentially lower SAR. In this study, multi-contrast CISS imaging was investigated for prostate imaging. VERSE pulses were implemented to reduce SAR. Results show good contrast in the prostate between the peripheral and transitional zones, comparable to that observed in TSE images. The use of VERSE pulses greatly reduces SAR and maintains contrast.
