What are Synthetic Medical Images?
Images generated by AI or algorithms, not captured by traditional imaging methods (e.g., MRI, CT).
Built using techniques like generative adversarial networks (GANs), variational autoencoders (VAEs), and diffusion models.
They mimic real medical images without using actual patient data.
Advantages of Synthetic Images
Intra- and Inter-Modality Translation: Can generate images across different types of scans (e.g., creating CT from MRI), filling gaps when certain scans are missing.
No real patient data is used, avoiding privacy concerns in data sharing and collaboration.
Reduces the time and cost associated with collecting real medical data.
Challenges Ahead
Risk of creating deepfakes that can mislead diagnoses or enable fraud.
May not capture the complexities of real medical conditions, leading to inaccurate representations.
Over reliance on synthetic images could blur the line between real and generated data, affecting diagnostic accuracy.
Way Forward
Close work between clinicians and AI developers to improve the quality and utility of synthetic images.
Ensuring regulatory and ethical standards are upheld in the use of AI-generated images.
Emphasizing cautious optimism to leverage the benefits of synthetic images without compromising real-world healthcare integrity.
