Fat-saturated T2-weighted Imaging with Slice Encoding for Metal Artifact Correction (SEMAC) at 3T

Magnetic resonance (MR) imaging plays an important role in the postoperative evaluation of patients. Fluid sensitive fat-suppressed MR imaging is especially important in postoperative evaluation. However, metallic artifacts are inevitable with MR imaging, and these metallic artifacts are aggravated by using fat-saturation. We thought the combination of advanced metal-artifact-reducing MR technique and fat suppression would be useful in metallic MR imaging. Considering the advantages of 3T MR imaging of the spine such as an increase in SNR with optimized diagnostic quality and improved clinical impact, implementing fat-suppressed SEMAC-corrected at 3T MR is a major goal in metallic MR imaging.
