Summary
This study presents a deep learning platform to help diagnose canine cardiomegaly using X-ray images. The system accurately identifies key points to calculate the vertebral heart score, aiding veterinarians in clinical evaluations.
Area of Science:
- Veterinary Medicine
- Medical Imaging
- Artificial Intelligence
Background:
- Cardiomegaly is a primary indicator of heart disease in dogs, often diagnosed via imaging.
- Deep learning shows significant promise for advancing diagnostic capabilities in veterinary medicine.
Purpose of the Study:
- To develop and validate a deep learning-assisted platform for diagnosing canine cardiomegaly.
- To improve the accuracy and efficiency of canine heart size evaluation using medical imaging.
Main Methods:
- Utilized HRNet (high resolution network) for detecting 16 key points on canine lateral X-ray images.
- Trained and validated the model on 2274 X-ray images, with external testing on 396 images.
- Implemented a post-processing step to refine key point detection accuracy.
Main Results:
- Achieved an initial average performance (AP) of 86.4% for key point detection.
- Enhanced AP to 90.9% after applying a post-processing correction procedure.
- Demonstrated the system's effectiveness in a clinical context for evaluating canine cardiomegaly.
Conclusions:
- The developed deep learning platform provides a clinically applicable tool for assisting in canine cardiomegaly diagnosis.
- The system's high accuracy in key point detection and VHS calculation supports its utility in veterinary practice.
- This technology has the potential to enhance diagnostic workflows for canine heart conditions.
