The availability of high field 3T clinical scanners enables higher resolution coronary vessel wall imaging. The use of more SNR-efficient spiral sequences together with the local inversion technique would combine the advantage of high field MRI with the ability of 3D imaging of the coronary vessel wall. The main challenge to be overcome is the increased field inhomogeneity at 3T. Therefore the of correct f0 and shim values are of high importance. In this study we sought to optimize the sequence for 3T and investigated the impact of the f0 and shimming trigger delay on image quality.
