Typically 'MRA of the Brain' or 'MRA Head'. Include contrast status if specified."},"clinicalHistory":{"defaultText":"[Patient-specific — populated at report time]","aiInstructions":"Ask the user for: patient age, sex, presenting complaint, relevant clinical history, and reason for the exam. This section contextualizes the entire report. Always include it."},"comparison":{"defaultText":"No prior studies available for comparison.","aiInstructions":"Extract comparison information directly from the report. If 'none' is stated, use default text. If prior studies are referenced, document the specific prior study details."},"technique":{"defaultText":"MRA of the head was performed using 3D time-of-flight technique without intravenous gadolinium. Multiple 3D MIP reconstructions were obtained.","aiInstructions":"Document the specific MRA technique used (e.g., time-of-flight, contrast-enhanced). Note whether gadolinium was used. Include any additional reconstructions or post-processing techniques mentioned."},"findings":{"defaultText":"Evaluation of the intracranial vasculature demonstrates normal flow-related enhancement without evidence of hemodynamically significant stenosis, occlusion, or aneurysm.","aiInstructions":"Organize findings by vascular territory. Begin with anterior circulation, then posterior circulation, then specific assessment of circle of Willis.

Collect patient clinical history from the user (age, sex, clinical indication).","2. Confirm whether prior studies are available for comparison.","3. For the Technique section, use defaultText or adapt based on actual acquisition parameters.","4. For each field in sections.findings.fields: ask the user for the finding or infer from clinical context. Use defaultText if the structure is normal.","5. Generate the Impression by summarizing the most significant findings from step 4.","6. Use the aiInstructions for each section to guide the depth and format of the content.","7.
