At an occlusive level, there were no false positives or false negatives. Vessels were reported 100% accurately when looking at occlusion.

Accuracy is the proportion of true results (both true positives and true negatives) in the study.
Precision is the proportion of the true positives against all the positive results (both true positives and false positives) in the study.
