Detection of Spinal Cord Lesions Using the MP2RAGE Sequence in Inflammatory Diseases of the Neuraxis

Brief summary (registry, in English)

Since the last revision of the MRI guidelines in multiple sclerosis (MS, MAGNIMS) and the McDonald criteria in 2017, all spinal cord lesions must be counted to increase the sensitivity and specificity of the diagnosis of MS. Focal lesions of the spinal cord are more frequently located in the cervical segments than in the lower segments of the spinal cord and occupy the lateral and posterior columns, although the central grey matter may not be spared. Cervical involvement is difficult to study because of the small size of the lesions and the loss of signal in the cervical region. As a result, the detection of cervical lesions on MRI is sub-optimal. In this context, standardised acquisition protocols have been proposed. For MRI of the spinal cord, at least two of the following sagittal sequences are recommended: T2, STIR, double inversion recovery, T1 with gadolinium injection, and/or T2 axial acquisitions. Recently, our team validated the superiority of 3D PSIR and 3D FGAPSIR sequences, which offer better detection performance than T2 and STIR on 3 Tesla MRI. Other studies have also shown the contribution of the MP2RAGE sequence to the detection of spinal cord lesions in MS, compared with the set of sequences classically recommended. The MP2RAGE sequence is a T1 sequence, which creates a composite image, limiting field inhomogeneity bias while providing a quantitative T1 map. It has recently been optimised for the spinal cord, and has been only minimally evaluated in the context of MS. The aim of this study is to evaluate the effectiveness of the MP2RAGE sequence in comparison with the set of conventional sequences recommended for the detection of spinal cord lesions in MS patients.
