3 T MRI relaxometry detects T2 prolongation in the cerebral normal-appearing white matter in multiple sclerosis
2009
NeuroImage
Preserved Fulltext
MRI at 3 T has increased sensitivity in detecting overt multiple sclerosis (MS) brain lesions; a growing body of data suggests clinically relevant damage occurs in the normal-appearing white matter (NAWM ...
We tested a novel pulse sequence to determine whether 3 T MRI spin-spin relaxometry detected damage in NAWM of MS patients (n = 13) vs. age-matched normal controls [(NL) (n = 11)]. ...
