  "img_finding": "Image findings: ventricular volume measures 21,951 mm³, 40.6% below the reference mean. With a Z-score of -1.10 (13.6th percentile), this represents mild atrophy; hippocampal volume measures 7,213 mm³, 11.1% above the reference mean. With a Z-score of 0.89 (81.2th percentile), this represents normal volume ; whole brain volume measures 1,052,080 mm³, 13.3% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement; entorhinal cortex volume measures 4,505 mm³, 30.1% above the reference mean. With a Z-score of 1.63 (94.8th percentile), this represents moderate enlargement; fusiform gyrus volume measures 16,229 mm³, 0.7% above the reference mean. With a Z-score of 0.06 (52.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,859 mm³, 4.6% above the reference mean. With a Z-score of 0.41 (65.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume data shows mild ventricular atrophy but otherwise normal or enlarged volumes in key regions (hippocampus, entorhinal cortex, fusiform gyrus, middle temporal gyrus). Cognitive scores (MMSE 29, MoCA 29) are intact, and APOE4 status (heterozygous) does not strongly suggest high risk in isolation.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
