Brief summary
The goal of this study is to learn if AI-generated video explanations help people better understand their radiology reports. The main question it aims to answer is: Do AI-generated videos help participants understand their medical imaging results better than written reports alone? Participants will send their own radiology images and written reports to the research team; receive a personalized AI-generated video that explains their results in easy-to-understand language; watch their video explanation (about 1-5 minutes long); and complete 15-minute online survey about how well the video helped them understand their results.
Interventions
OTHERAI-Generated Video Radiology Report Explanation
Participants receive a personalized video explanation of their own radiology imaging results, generated using artificial intelligence technology. The AI converts the participant's existing written radiology report into an easy-to-understand video format featuring an avatar narrator. Each video is approximately 1-5 minutes long and explains the participant's specific imaging findings in plain language. All AI-generated videos are reviewed by qualified medical personnel before delivery to ensure accuracy and prevent misleading information. Participants watch their personalized video and then complete survey to evaluate how well the video helped them understand their radiology results compared to the original written report.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Patient Understanding of Radiology Report After AI-Generated Video Explanation | Baseline (before viewing video) and immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Change in patient-reported understanding score measured by the question How would you rank your understanding of the radiology report? assessed before and after viewing the AI-generated video explanation. Scores range from 1 (Not at all) to 5 (Very well), where higher scores indicate better understanding. The primary outcome is calculated as the difference between post-video and pre-video understanding scores, with positive values indicating improved understanding. |
| Change in Patient Understanding of Radiology Images After AI-Generated Video Explanation | Baseline (before viewing video) and immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Change in patient-reported understanding score measured by the question How would you rank your understanding of the radiology image? assessed before and after viewing the AI-generated video explanation. Scores range from 1 (Not at all) to 5 (Very well), where higher scores indicate better understanding. The outcome is calculated as the difference between post-video and pre-video understanding scores, with positive values indicating improved understanding. |
Secondary

|---|---|---|
| Perceived Ease of Use of AI-Generated Video Radiology Explanation | Immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Patient-reported ease of use score measured by the statement The AI video explanation is easy to follow and interact with assessed after viewing the AI-generated video explanation. Scores range from 1 (Strongly Disagree) to 5 (Strongly Agree), where higher scores indicate greater perceived ease of use of the AI video explanation. |
| Overall Patient Experience with AI-Generated Video Radiology Explanation | Immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Patient-reported overall experience score measured by the question Overall, how was your experience with the video report? assessed after viewing the AI-generated video explanation. Scores range from 1 (Poor) to 5 (Excellent), where higher scores indicate better overall experience with the AI video explanation. |
| Patient Likelihood to Recommend AI-Generated Video Radiology Explanations | Immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video)RetryClaude can make mistakes. Please double-check responses. | Patient-reported recommendation likelihood score measured by the statement I would recommend this type of video explanation to other people to understand their radiology findings assessed after viewing the AI-generated video explanation. Scores range from 1 (Strongly Disagree) to 5 (Strongly Agree), where higher scores indicate greater likelihood to recommend the AI video explanation to others. |
| Change in Patient Knowledge of Body Part Described in Radiology Report After AI-Generated Video Explanation | Baseline (before viewing video) and immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Change in patient knowledge measured by the question Do you know which part of your body was described in the report? assessed before and after viewing the AI-generated video explanation. Responses are Yes/No, where the outcome is calculated as the proportion of participants who gained knowledge (changed from No to Yes) after viewing the video. |
| Understanding of Finding Significance | Baseline (before viewing video) and immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Change in participant's understanding of the significance of their radiology findings measured on a 5-point Likert scale (1=Not at all to 5=Very well), comparing pre-video to post-video scores |
| Change in Ability to Explain Radiology Findings to Family Members After AI-Generated Video Explanation | Baseline (before viewing video) and immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Change in patient-reported confidence score measured by the statement I can explain the main findings of my radiology report to my family members assessed before and after viewing the AI-generated video explanation. Scores range from 1 (Strongly Disagree) to 5 (Strongly Agree), where higher scores indicate greater confidence in explaining findings. The outcome is calculated as the difference between post-video and pre-video confidence scores, with positive values indicating improved confidence. |
| Change in Patient Confidence Discussing Radiology Results with Healthcare Provider After AI-Generated Video Explanation | Baseline (before viewing video) and immediately after viewing the AI-generated video explanation (within 24 hours of receiving the video) | Change in patient-reported confidence score measured by the statement I feel confident discussing my radiology results with my healthcare provider assessed before and after viewing the AI-generated video explanation.
