AI-Based Video Radiology Reports Enhance Patient Understanding
May 22, 2025
Harvard researchers presented an AI system that generates video radiology reports rated highly by radiologists for patient communication.
Key Details
- The ReXplain AI system creates patient-friendly video radiology reports using a large-language model, image segmentation, and conversational avatars.
- Tested with five radiologists and 10 CT video reports, the tool received 98-100% positive agreement on understandability and accuracy.
- Radiologists strongly agreed that image explanations and normal comparisons improved comprehension.
- 80% were comfortable providing videos to patients, with some hesitance for pre-visit distribution (60%).
- Feedback on 3D image rendering was mixed (50%).
- Further patient-centered studies are planned.
Why It Matters
Improving patient understanding of radiology results is a key unmet need; AI-generated multimedia reports could bridge the gap between medical reports and patient comprehension, helping radiology demonstrate direct value to patients.
