T1- vs. T2-based MRI measures of spinal cord volume in healthy subjects and patients with multiple sclerosis

Background: The reliable and efficient measurement of spinal cord atrophy is of growing interest in monitoring disease progression in multiple sclerosis (MS). Methods: We compared T1- and T2-weighted MRI for measuring cervical spinal cord volume in 31 patients with MS and 18 age-matched controls (NC) from T1-weighted gradient recalled echo and T2-weighted fast spin-echo 1.5 T axial acquisitions. The two sequences were matched on slice thickness, signal averages and voxel size. An active surface software tool determined the normalized mean cervical cord cross-sectional area. Results: T1-derived cord areas were higher than T2 areas in the whole cohort (estimated mean difference = 7.03 mm 2 (8.89 %); 95 % Confidence Interval (CI): 5.91, 8.14; p  (Source: BMC Ne…
