Abstract

Artificial intelligence has emerged as a powerful tool in medical imaging, improving diagnostic accuracy, workflow efficiency, and early disease detection.

1. Introduction

Medical imaging plays a critical role in modern healthcare, and AI systems are now augmenting expert interpretation in multiple modalities.

2. AI Techniques in Medical Imaging

Deep learning, transfer learning, and assistive image enhancement are widely used to improve detection, segmentation, and triage support.
  • Convolutional Neural Networks
  • Transfer Learning
  • GAN-based enhancement
  • Reinforcement Learning

3. Applications

AI supports MRI, CT, ultrasound, and X-ray interpretation through faster detection and improved reporting consistency.

4. Challenges

Clinical AI still faces interoperability, fairness, security, and validation issues across diverse populations and devices.
  • Limited labeled datasets
  • High computational cost
  • Lack of standardization
  • Privacy concerns

Key Takeaway

AI will not replace radiologists but will empower them to make faster and more accurate decisions.

5. Future Directions

Future work should focus on explainability, multi-modal models, and stronger generalization across institutions.

6. Conclusion

AI can improve patient outcomes when biomedical researchers and healthcare teams collaborate responsibly.
