STI is sensitive to tissue microstructure and can detect subtle changes in disease states. However, STI remains a challenging protocol due to the physical reorientation with respect to the magnetic field. Current studies of the heart and kidney are limited to ex-vivo imaging. In this study, we present frequency tensor imaging (FTI) at a single image acquisition without rotating the object. FTI takes advantage of tissue structure already pointing in multiple directions with respect to the magnetic field in a single orientation dataset. This technique offers the potential for susceptibility-based tensor imaging of the abdomen in the clinic.
