Explainable Cardiomegaly Screening
A frontal chest X-ray system that combines anatomical segmentation, cardiothoracic measurements, CNN evidence, and tabular classification instead of relying on a single opaque score.

Methods and evidence
Explainable Cardiomegaly Screening

- Data
- Project materials describe PadChest, MIMIC-CXR, CheXpert, VinDr-CXR, NIH ChestX-ray14, and CheXmask-derived masks.
- Models
- U-Net++ for the heart, DeepLabV3+ with ResNet101 for the lungs, and LightGBM over CTR, area features, and CNN probability.
- Reported results
- Heart IoU 87.26%; right/left lung IoU 91.11%/89.53%; classifier F1 91.4%; CTR SMAPE 7.5%.
Interpretability: the report includes cardiothoracic ratio, heart/lung area features, Grad-CAM, and SHAP. It also documents StyleGAN2-ADA synthetic-data experiments.
