Abstract

Background: Multiple sclerosis (MS) is a complicated autoimmune illness with a wide range of symptoms. The aim of the present study was to describe the additional value of high field-strength (3 tesla) MR imaging system in evaluation and monitoring of multiple sclerosis CNS lesions. Methods: This study was conducted on 25 MS patients, were exposed to MRI protocol for multiple sclerosis with post contrast (gadolinium) injection images. Scans were performed during 2 sessions separated by 1 to 3 days on both 1.5T and 3.0 T. Results: The mean age of the studied patients was 30 years, the number of lesions showed significant differences between 1.5 Tesla and 3 Tesla with wider ranges of lesions was detected using 3 Tesla at these sites: periventricular (P-value = 0.005), juxta cortical (P-value = 0.01), deep white matter (P-value = 0.016), spinal cord (P-value = 0.041). No significant difference was reported at the infratentorial site (P-value = 0.054). Regarding all lesions, the mean number of lesions was significantly higher using 3 Tesla (16 lesions) than 1.5 Tesla (13 lesions). P-value was
