3D PSIR MRI at 3 Tesla improves detection of spinal cord lesions in multiple sclerosis

Spinal imaging in multiple sclerosis remains challenging because of its small size and numerous artifacts. To compare 3D Phase-Sensitive Inversion Recovery (PSIR) to a conventional dataset of 3D Short Tau Inversion Recovery (STIR) and T2-weighted imaging at 3 Tesla to detect multiple sclerosis spinal cord lesions. This prospective single-center study was approved by a national research ethics board and included 54 patients (median age 44)...
