perirolandic

On turbo FLAIR images the PRC generally has a low SI in the neurologically normal brain, and this helps as an additional landmark in identifying the sensorimotor cortex 1).

The perirolandic low signal intensity seen on T2-weighted MR images is located exactly in the anatomic sensorimotor cortex in normal brains, whereas a mismatch can occur in abnormal brains 2).
