To examine the relationship between inflammation and brain atrophy in patients with a clinically isolated syndrome (CIS) suggestive of multiple sclerosis (MS).

Monthly triple-dose gadolinium (Gd/DTPA)-enhanced MRI scans over 6 months were obtained in 62 consecutive CIS patients with an abnormal baseline MRI scan. Subsequently MRI was performed at months 12 and 18. Patients who developed a clinically definite MS (i. e., a second clinical episode) ended the study at the time of the relapse. For each scan, the number and volume of newly active lesions (Gd-enhancement/new or newly enlarging T2 lesion that did not enhance), and the number and volume of T2 hyperintense lesions (T2-LL) and T1-black holes (T1- LL) were calculated. The percentage of brain volume changes (PBVC) was assessed using a fully …
