  1. *Adler grade: Level 0: no blood flow in the lesion; Level 1:a small amount of blood flow, with 1 or 2 punctured or thin rod blood flow; Level 2: moderate blood flow, one major blood vessel can be seen, its length is close to or beyond the radius of the lesion or 3 ~ 4 punctured or fine rod-shaped blood vessels; Level 3: abundant blood flow, visible more than 4 blood vessels or interconnected, intertwined into a network. Adler grading observes the distribution and richness of blood flow, finds the section with the most abundant blood flow, calculates the number of blood vessels. Te definition ofAlder grading change is whether grading decreases after NAC.
