Dental MRI is a new and promising diagnostic tool. Unfortunately, in presence of implants image quality is impaired by failure of fat suppression and susceptibility artifacts. Here, we for the first time systematically evaluated fat saturated MR sequences for artifact reduction for dental MRI. Smallest artifact volume was noted for SEMAC-STIR and TSE-STIR sequences. But, higher and isotropic resolution was only achieved with MSVAT-SPACE-STIR sequence. No artifact reduction was measured for SEMAC-STIR compared to standard TSE-STIR. In contrast, MSVAT-SPACE-STIR reduced artifacts up to 70% compared to standard SPACE-STIR. Since imaging of dental structures benefit from isotropic high resolution MSVAT-SPACE-STIR is advantageous.
