In this study, a novel double inversion recovery pulse
sequence was applied in patients with Multiple
Sclerosis, suppressing signal from CSF and gray matter.
We show a new ring pattern of signal change surrounding
WM lesions that is not seen on standard DIR.
Approximately 50% of the identified lesions reveal this
rim pattern of hypo-intense signal change, most
prominent in larger and periventricular lesions.
