Signal
abnormalities in multiple sclerosis such as neocortical and juxtacortical
lesions can be visualized best using a double inversion recovery (DIR)
sequence. DIR sequences are based on T1 filtering and aim on suppressing
signal from white matter and cerebrospinal fluid. We here investigated,
whether the application of additional MT saturation pulses can further
improve the contrast between cortex, white matter and embedded lesions. The
new sequence was evaluated in the brain of healthy volunteers and multiple
sclerosis patients.
