Let your healthcare provider know if you have or use any implanted medical devices, such as hearing aids. Single-shot T2W imaging combined with fat suppression employing the SPAIR technique provides optimal sensitivity and specificity for active Crohns disease.15,16,23 Earlier studies either did not use fat-suppressed T2 or did not use optimized fat suppression and may not have appreciated the full utility of MRE.4,36,37 Other forms of fat suppression, such as simple inversion-recovery or chemical shift spoiling, typically demonstrate higher noise, less uniform fat suppression, and increased through-plane motion sensitivity to bowel peristalsis.23 Although MRE is relatively insensitive to early disease, or disease confined to the mucosa, it is effective at evaluating the severity and extent of submucosal pathology and extra-intestinal complications.38 T2W imaging with fat saturation has shown high accuracy for measuring inflammation and acute disease activity compared to endoscopy, biopsy, and CT.
