“…To overcome challenges with spine imaging and increase both the sensitivity and specificity to detect inflammatory medullary lesions, the literature indicates a few other reliable MR imaging sequences, such as proton-density imaging, 10 STIR, 11,12 phasesensitive T1-weighted inversion-recovery MR imaging (PST1-IR), 13 Multi-Echo Recombined Gradient Echo (MERGE; GE Healthcare, Milwaukee, Wisconsin), 14 white matter-suppressed T1 inversion recovery, 15 double inversion recovery, 16 and MPRAGE. 17 Recent studies have shown that the phase-sensitive inversion recovery (PSIR) sequence, consisting of a heavily T1weighted inversion recovery combined with phase-sensitive reconstruction, 13,18 had the highest lesion-to-cord contrast and lesion-limit definition.…”
