AI-Based Video Radiology Reports Enhance Patient Understanding

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.
