Dawson Fingers Multiple Sclerosis

Fig. 11.22 a This parasagittal MR image shows the typical centripetal orientation of the demyelination plaques along the long axis of medullary veins to their best advantage. This phenomenon is sometimes called "Dawson's fingers." b The lesions have a high signal in T2-weighted sequences (arrow). c In an acute relapse, the lesions tend to accumulate contrast in their periphery (arrow).
