Summary

The goal of this clinical trial is to learn if a summary written by artificial intelligence (AI) helps adults understand brain MRI reports for headaches. The main question it aims to answer is: "Does adding a simple summary help readers correctly understand if a cause for the headache was found in the report?" Researchers will compare standard MRI reports to reports that include an AI-generated explanation to see if the extra summary improves understanding.

Participants will:

Read 6 fictional brain MRI reports online. Answer questions to check if they understood the results. Rate their satisfaction and if they feel they would need to ask a doctor for help.

LLM-generated lay summary

Participants assigned to this group read fictional brain MRI reports that include an additional summary paragraph generated by an artificial intelligence tool. Specifically, an open-weights Large Language Model (LLM) with fewer than 100 billion parameters is used, hosted locally on a secure server to ensure data privacy. This model generates a short synthesis designed to be clear and structured for non-medical readers. This summary is inserted into the report under the heading Synthesis intended for the patient and non-radiologist physician. The intervention consists solely of this added text; the standard medical content of the report remains unchanged.
