The purpose of our study was to improve 3D-STIR for TRANCE non-contrast MR angiography in clinical 3.0T MR system using modified hyperbolic secant (HS4) pulses. the higher field strength poses additional challenges to 3D STIR, including wider offset frequency between water and fat combined with larger B0 and B1 inhomogeneities, which reduce the reliability of fat suppression. 3D STIR (TRANCE) with HS4 pulse has clearly improved fat suppression due to B0/B1 inhomogeneous compared with conventional HS pulse in clinical.
