T1/T2 mapping and extracellular volume (ECV)
4 studies reported T1 values [102,104–106]. Native T1 was increased
compared with controls in 2 studies [102,105]. One study showed
normal T1 values as compared with controls [106] and one study had
no comparators [104]. Similarly, native T2 values were elevated
compared with controls [102,105,106]. ECV was reported in 3 studies
[104–106] and was significantly elevated compared with controls
[106] or patients with negative MRI [105]. Reported values for
ECV were ranging between 28 to 36% [104,105]. 1 study reported that
ECV was increased in mid-septum [106].
