Area of Science:

Medical Imaging
Artificial Intelligence in Healthcare
Oncology

Background:

Accurate near-term breast cancer risk prediction is crucial for early detection and intervention.
Traditional mammographic analysis relies on grayscale value (GV) features, which may not capture all relevant information.

Purpose of the Study:

To enhance the accuracy of near-term breast cancer risk prediction.
To evaluate a novel mammographic image conversion method combined with a two-stage artificial neural network (ANN) classification scheme.

Main Methods:

Mammographic images from 168 screening cases were analyzed.
A new method converted grayscale value (GV)-based images to optical density (OD)-based images.
A two-stage ANN classification scheme fused features from both GV and OD images.

Main Results:

The proposed two-stage classification scheme achieved an area under the receiver operating characteristic curve (AUC) of 0.816 ± 0.071.
This performance was significantly higher than using GV features (AUC = 0.669 ± 0.099) or OD features (AUC = 0.646 ± 0.099) alone (P < .05).

Conclusions:

Optical density (OD) image conversion provides complementary information to standard grayscale analysis.
Fusion of image features from both GV and OD mammograms significantly improves near-term breast cancer risk prediction accuracy.
