Lesion Detection Using T1-Weighted Mri: A New Approach Based On Functional Cortical Rois |
Abstract | ||
---|---|---|
Accurate and precise detection of brain lesions on MR images is important for relating lesion locations to impaired behaviors. In this paper, we propose a method to detect lesion voxels on each functional cortical ROI (Region of Interest) independently using only T1-weighted MR images (T1-MRI). In contrast to existing automatic lesion detection methods, which typically detect lesion voxels on the whole MR image or on gray matter (GM)/white matter (WM), we show that the proposed functional cortical ROI based method can lead to better lesion-detection performance. We evaluate the proposed method using an in-house dataset with 60 chronic stroke patients. Using leave-one-subject-out cross validation, the proposed method can achieve an average Dice coefficient of 0.74 +/- 0.11 and outperform three state-of-the-art methods by more than 0.05. |
