Magnetic resonance imaging of spinal cord in multiple sclerosis by fluid-attenuated inversion recovery.
Magnetic resonance imaging examination of the upper spinal cord was done in sixteen adult patients with clinically definite multiple sclerosis (MS) by T2 weighted fluid attenuated inversion recovery (FLAIR) scanning in which the signal from cerebrospinal fluid was suppressed. These scans were compared with matched images obtained with conventional T1 and T2 weighted pulse sequences (including contrast enhancement). 6 lesions (five patients) were seen with the conventional scans and 37 lesions (fourteen patients) were seen with the FLAIR scans. The FLAIR sequence considerably improves the ability of MRI to demonstrate spinal involvement in MS.
