  "img_finding": "Image findings: whole brain volume measures 1,002,660 mm³, 2.6% below the reference mean. With a Z-score of -0.32 (37.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,898 mm³, 0.1% above the reference mean. With a Z-score of 0.01 (50.4th percentile), this represents normal volume ; fusiform gyrus volume measures 17,399 mm³, 4.5% below the reference mean. With a Z-score of -0.50 (30.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,144 mm³, 3.0% above the reference mean. With a Z-score of 0.27 (60.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures (whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are all within normal ranges, with Z-scores close to zero and percentiles near the 50th percentile. Cognitive scores (MMSE 26, MoCA 25) are slightly below optimal but still within normal limits for age. No significant biomarkers (APOE4 negative, AV45 normal) suggest Alzheimer's pathology.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
