This is an online calculator and viewer for brain lesion scores and atlases. The following scores can be calculated: • Location impact score for acute infarcts. • Network impact score for acute infarcts. • Strategic WMH score for white matter hyperintensities. Further information regarding these scores is provided elsewhere on the website. To get started with calculating the scores, press the 'upload' button below, select your lesion map in MNI-152 space (resolution has to be 1×1×1 mm), set the appropriate lesion type and press confirm. Clicking the scores in the table will copy them to the clipboard. NB: A batch tool for calculating scores for large datasets will be available in the near future.
