How is AI Changing Medical ImagingWhen applied to echocardiography, the most common type of cardiovascular imaging, AI techniques such as convolutional neural networks could identify subtle structural and functional cardiac anomalies with significant clinical correlation.

FREMONT, CA: Many AI imaging studies currently calculate sensitivity and specificity to estimate diagnostic precision, while others measure clinically relevant outcomes.  More important outcome factors include new diagnoses of advanced illness, disease needing care, or conditions likely to impair long-term survival, as AI also detects small picture alterations. Clinically significant events—symptoms, the need for disease-modifying treatment, and mortality—have a significant impact on the quality of life and should be the focus of AI-based research.

When applied to echocardiography, the most common type of cardiovascular imaging, AI techniques such as convolutional neural networks could identify subtle structural and functional cardiac anomalies with significant clinical correlation.

Another case in point is the treatment of aortic stenosis patients. There is currently no evidence that valve replacement is better than medical therapy for patients with non-severe aortic stenosis. AI-assisted echocardiography, computed tomography, or MRI may provide granular assessments of annular conformation, leaflet mobility, and outflow tract to distinguish patients with less serious stenosis who may benefit from surgical or percutaneous intervention over medical management.

It is just as critical, if not more so, to spot changes in left ventricular activity, fibrosis, or remodeling that might signify the need for earlier intervention. AI's improved reading performance may increase patient selection for intervention by detecting small systemic or dynamic changes related to poor outcomes. The key point is to provide reliable AI classification of aortic stenosis severity based on scientifically validated input, which allows for the generation of new findings that are congruent with the disease phenotype, ensuring that patients with a serious disease are correctly captured. Those with moderate disease are not erroneously reclassified into a high-risk category. Cancer detection and characterization is another high-yield niche for AI imaging. High-resolution quantitative analysis of fine structural image changes may be used to predict the likelihood of malignancy and tumor kinetics and help tailor management strategies.
