PURPOSE: To determine the presence of small lesions in the pyramidal tract in patients with amyotrophic lateral sclerosis (ALS) by using magnetization-transfer (MT) measurements and MR imaging. METHODS: MT ratios (MTRs) were measured in the posterior limb of the internal capsule in nine patients with ALS and in nine healthy volunteers. RESULTS: The mean value of MTRs (%) in patients with ALS was 15.76 +/- 1.48, while that of the control subjects was 19.83 +/- 1.54. The difference was statistically significant. CONCLUSIONS: MT measurements are useful for detecting abnormalities associated with degeneration of the pyramidal tract in patients with ALS.
