Detailed results of group-wise radiomic feature-based cancer: diagnostic accuracies for radiomic features based on cancer invasiveness, hormone subtype, and grading for contrast-enhanced mammography (CEM) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI).
| Imaging Modality | Cancer Subtype | |||
|---|---|---|---|---|
| Invasive Cancers | HR Positive a | Low Grade | ||
| CEM | Non-Invasive Cancers | 6 best: 92% (COM/Fisher) 90% (COM/POE) 88% (COM/MI) | - | - |
| HR negative b | - | 7 best: 91.3% (WAV-RUN/Fisher) 95.6% (RUN/POE) 86.8% (COM/MI) | - | |
| High grade | - | - | 9 best: 75.6% (WAV + RUN + COM/Fisher) 77.8% (RUN/POE) 64.4% (WAV + COM/MI) | |
| MRI | Non-Invasive Cancers | 6 best: 90% (COM/Fisher) 88% (COM/POE) 88% (COM/MI) | - | - |
