I appreciate the list. I would consider image registration and volume mapping important, but on the lower end of what people consider important contributions from "AI."
ChatGPT
You're correct, and I apologize for the oversight. Image registration and volume mapping are indeed essential applications of AI in cardiovascular imaging, and they play a significant role in enhancing the accuracy and utility of imaging data. These applications help align and fuse images from different modalities or time points, enabling comprehensive and integrated assessments of the cardiovascular system.
Image Registration: Image registration involves aligning images acquired from various sources or at different time points, which is crucial for multi-modal imaging and longitudinal studies. AI-based registration algorithms can efficiently match corresponding structures, allowing for more accurate and informative comparisons.
Volume Mapping: AI can assist in generating 3D reconstructions and volume mapping of the heart and blood vessels. This provides a comprehensive view of the cardiovascular anatomy and aids in identifying complex structures or anomalies that might be challenging to visualize in 2D images alone.
Both image registration and volume mapping contribute significantly to cardiovascular imaging by improving the quality of data analysis and facilitating better understanding of cardiac morphology and function. These applications are particularly valuable in research studies, treatment planning, and follow-up assessments for patients with cardiovascular diseases.
I work in the field of cutting edge pathology, laboratory medicine, and genomics. I often feel that radiology is farther ahead of us in adopting or preparing for transformational change, from AI. Of course, radiology went all-digital in the 1990s (especially driven by CT and MRI, which start out digital, and were then only transferred to large sheets of film, for storage and viewing on a light box!!). And FDA and others are rapidly bringing AI into radiology, such as computer assisted lesion detection in mammography. One of the main journals, Journal of the American College of Radiology, is awash with a plethora of articles, not only about applications of AI, but, also, forward-thinking strategies for AI. From the DEY article above, pm CARDIOVASCULAR IMAGING, what insights can you give us in the field of genomics and pathology? What are DEY-type people thinking (in cardiovascular imaging) that we futurists in genomics or pathology should begin thinking too? How can we cross pollinate a view of the future from DEY and Cardiovascular imaging into laboratory medicine?

What would be some key differences? Where can AI in cardiovascular imaging go, (per DEY et al) that AI in pathology (genomics) cannot follow?
ChatGPT
While there are many similarities in the application of AI between cardiovascular imaging and pathology (genomics), there are also some key differences due to the nature of the data and the clinical context. Here are some areas where AI in cardiovascular imaging might have unique opportunities that may not directly apply to AI in pathology (genomics):
Image Analysis Complexity: Cardiovascular imaging involves complex and high-dimensional image data, such as CT scans, MRIs, and echocardiograms. AI can assist in tasks like image segmentation, feature extraction, and 3D reconstruction, which are specific to image analysis. In pathology (genomics), AI focuses more on data analysis, pattern recognition, and prediction based on genetic information, which may not involve image-based complexities.
Real-Time Decision Support: In cardiovascular imaging, AI can provide real-time decision support to radiologists or cardiologists during image interpretation, allowing quick and accurate diagnoses. This real-time application is less common in pathology, where genomics data analysis often occurs offline and may require time for data processing and interpretation.
Integration with Imaging Devices: AI in cardiovascular imaging can be seamlessly integrated into existing imaging devices and workstations, facilitating its adoption in clinical practice. In pathology, integrating AI with laboratory equipment might have different technical and operational challenges.
Continuous Monitoring and Updates: Cardiovascular imaging involves continuous patient monitoring over time, and AI can play a role in providing dynamic insights and tracking disease progression. In genomics, AI's continuous monitoring might involve longitudinal analysis of genetic data to understand disease evolution and treatment responses.
Imaging Biomarkers: AI in cardiovascular imaging can identify and quantify imaging biomarkers related to various cardiovascular diseases, aiding in risk assessment and treatment planning. In pathology, AI can predict disease risk based on genetic information but might not directly quantify imaging biomarkers.
Visualization and Communication: AI in cardiovascular imaging can generate visualizations and reports that are easily interpretable and communicable to clinicians and patients. In genomics, the output might involve genetic risk scores, variant predictions, or disease risk probabilities that require different modes of communication.
Interventional Applications: AI in cardiovascular imaging can assist in image-guided interventions, such as planning and navigating catheter-based procedures. In pathology (genomics), AI is less directly involved in real-time interventional decision-making.
Despite these differences, there are also areas of overlap and potential collaboration between AI in cardiovascular imaging and pathology (genomics). For example, both fields can benefit from AI-powered data analysis, predictive modeling, and clinical decision support. As AI technology continues to advance, there may be increasing opportunities for cross-disciplinary research and knowledge exchange to drive transformative changes in both cardiovascular imaging and pathology (genomics).
