Non-parametric Spearman correlation coefficient between the area (in % of the segment area) of the spread of fluorescent microspheres 1 h after intracisternal administration in different segments of the ventral surface of the brain and hemorrhagic score in the respective segments at different time following the induction of subarachnoid hemorrhage was calculated at different time following the SAH. Note the practical absence of correlation between the spread of fluorescence and hemorrhagic score.
