“…The RR MS cohort had a median [interquartile range (IQR)] age of 38 [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49], disease duration of 6.5 years [2][3][4][5][6][7][8][9][10][11][12][13], EDSS 3.5 (2.5-4.0), AI 2 [1][2][3], timed 25-foot walk 5.01 seconds (4.37-6.11) and 3 relapses [2][3][4][5] within the last two years. The SP MS cohort had a median age of 51 [41][42][43][44][45][46][47][48][49][50][51][52][53], disease duration of 20 years [12][13][14][15]…”

“…151 Such measures can detect diffuse damage in areas of the CNS that are free of overt lesions on conventional MRI scans. 94,[152][153][154][155][156][157][158][159][160][161] Furthermore, T1 mapping may be more sensitive than MTR in detecting tissue damage in NAWM. 94 The most common effect of MS on T1 relaxation is prolongation, which is believed to result from a variety of processes such as edema, demyelination, gliosis, and axonal loss in NAWM profound prolongation of T1 is seen when comparing patients with SPMS to patients with RRMS 160 and in patients with early RRMS versus normal controls.…”

“…Son yıllarda radyolojik tetkiklerden elde edilen görüntüler üzerinde Cavalieri ilkesine dayalı hacim hesaplama yöntemi kullanılarak, gerçekte üç boyutlu olan her yapının hacminin etkin ve tarafsız bir biçimde ölçüldüğü ve iki boyutlu görüntülerden kaynaklanan hatalardan uzak bir değerlendirmenin yapılabileceği gösterilmiştir (22,(23)(24)(25)(26). Cavalieri yönteminde önce ilgilenilen yapıdan, nesnenin tümünü kapsayacak şekilde, birbirine paralel kesitler alınır.…”
