The presence of normal-appearing brain tissue (NABT) changes was investigated in 30 first-degree relatives of patients with MS, using magnetization transfer ratio (MTR) histograms.
When compared with controls, relatives of patients with familial (p = 0.01) and sporadic (p = 0.01) MS had lower NABT MTR histogram peak heights.
This study suggests a reduction of
truly normal NABT in asymptomatic relatives of patients with MS.
