New AI Tool Helps Spot Skin Cancer Faster
27 Oct
Summary
- AI tool DEXI aids doctors in identifying skin cancers.
- It correctly identified nearly 94% of skin cancers.
- DEXI analyzes lesion features like asymmetry and color.
A new artificial intelligence imaging system, known as Dermoscopy Explainable Intelligence (DEXI), is now available to assist dermatologists in identifying skin cancers. This tool, detailed in Mayo Clinic Proceedings, analyzes skin lesions and assigns a score from zero to 10 based on their likelihood of being cancerous. DEXI achieved a near 94% accuracy in identifying skin cancers and was correct in about 75% of cases involving non-cancerous lesions.
The AI system was trained on over 66,000 skin images and evaluates features such as asymmetry, border irregularity, and color variations within lesions. In a study, DEXI's assessments were compared against those of dermatologists. Researchers proposed a score of 3.0 as a potential threshold for malignancy, guiding decisions on monitoring or biopsy. However, DEXI does not consider patient-specific factors like age or medical history, underscoring the need for its findings to be interpreted alongside clinical assessments.
