CBF maps from 4 subjects obtained with the reference algorithms, SCORE, and SCORE+. The CBF map of Subject 1 shows no visible artifact and all the algorithms performed comparably. The CBF maps of subjects 2,3 and 4 obtained from each of the reference algorithms have visible artifacts manifested by negative CBF values (indicated by yellow arrows). SCORE and SCORE+ showed reduced artifact in the resulting maps. However, artifacts indicated by red arrows in the CBF maps of subject 2 are not removed by any of the algorithms.
