Score Description
1 Poor. Unable to differentiate cardiovascular structures
2 Low. Cardiovascular structures can be slightly intuited.
3 Intermediate. Cardiovascular structures can be delineated.
4 Good. Good definition of cardiovascular structures.
5 Excellent. Optimal cardiovascular structures delineation.
