Optimal Breast Density Characterization Using a Three-Dimensional Automated Breast Densitometry System.

Relationship between VDG and Diagnostic Accuracy The diagnostic accuracy of MMG was 81.4% (359/441) among all patients (84.2% [48/57], 84.2% [148/173], and 77.3% [163/211] for patients in VDG: a + b, c, and d, respectively), highlighting a significant trend in which the diagnostic accuracy decreased with increasing VDG ( p = 0.0284).

A nonsignificant trend for a smaller size of invasion was observed in the VDG: a + b group ( p < 0.1), and no significant difference was noted in the VDG: d group ( p = 0.21) ( Figure 3 ). 3.5.
