Popis: | BACKGROUND: The assessment of brain atrophy in a clinical routine is not performed routinely in multiple sclerosis (MS). OBJECTIVES: To determine feasibility of brain atrophy measurement and its association with disability progression (DP), in MS patients followed in a clinical routine over 5 years. METHODS: 1,815 subjects, of which 1,514 MS and 137 with clinically isolated syndrome (CIS) patients, and 164 healthy individuals (HI) were collected retrospectively. Of 11,794 MRI brain scans included in the analysis, 8,423 MRIs were performed on a 3T and 3,371 MRIs on a 1.5T scanner. All patients received 3D T1-WI and T2-FLAIR exams at all time points of the study. Whole brain volume changes were measured by percentage brain volume change (PBVC) using SIENA and percentage normalized brain volume (NBV) change using SIENAX on 3D T1-WI, and percentage lateral ventricle volume (LVV) change using NeuroSTREAM on T2-FLAIR. Annualized rates were calculated. RESULTS: PBVC failed in 36.7% of the subjects, percentage NBV change in 19.2%, and percentage LVV change in 3.3%, because of protocol changes, poor scan quality, artifacts and anatomical variations. Annualized brain volume changes were significantly different between MS and HI for PBVC (p |
