MR Findings of Multiple Sclerosis in Spinal Cord
Abstract
- PURPOSE
To analyze the MR imaging features of multiple sclerosis (MS) in spinal cord.
MATERIALS AND METHODS
Nine MR (magnetic resonance) images of six patients with suspected MS were retrospectively evaluated in active phase (n=6) and inactive phase (n=3) before and after Gadolinium-DTPA administration.
RESULTS
In all patients with clinically active phase, plaques of spinal cord appeared as high signal intensity on T2-weighted image with isointense cord swelling on Tl-weighted images. All lesions were enhanced on Gd-DTPA enhanced
Tl-weighted images. The patterns of enhancement were nodular, circumferential rim-like, and segmental. On follow-up images in 3 patients who became clinically stable, all enhancing lesions disappeared.
CONCLUSION
MR is a good modality in detection of spinal MS, and Gd-DTPA-enhanced MR is valuable in differentiating active MS from stable MS.
