Visualization of cortical lesions on conventional MR
images is often challenging due to restricted
contrast-to-noise levels. Further, cerebrospinal fluid
(CSF) in the vicinity of lesions hampers lesion
detection. The here proposed combination of conventional
T2-weighted and FLAIR images doubles the
contrast-to-noise ratio, while providing suppression of
CSF signal. The enhanced contrast may aid automated
lesion segmentation and detection of cortical lesions.
