The researchers in this study looked prospectively at 37 MS patients,
who underwent multicontrast 7T MR imaging including 2D-T2WI, 3D-T1WI,
3D-FLAIR and GM-specific 3D-DIR. The sensitivity of conventional MRI
techniques to detect cortical lesions remains poor when compared with
histopathologic studies. Grey matter abnormalities strongly explain
cognitive and physical disability. Results showed that the 3D-FLAIR
detected the highest number of total cortical grey matter lesions at 7T.
The improved visibility of cortical abnormalities at DIR, seen at 1.5T
and at 3T did not hold in the 7T dataset.
