  "img_finding": "Image findings: ventricular volume measures 61,235 mm³, 59.0% above the reference mean. With a Z-score of 1.41 (92.1th percentile), this represents mild enlargement; hippocampal volume measures 7,495 mm³, 0.9% below the reference mean. With a Z-score of -0.08 (46.7th percentile), this represents normal volume ; whole brain volume measures 1,195,500 mm³, 10.8% above the reference mean. With a Z-score of 1.40 (91.9th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,595 mm³, 12.1% above the reference mean. With a Z-score of 0.82 (79.3th percentile), this represents normal volume ; fusiform gyrus volume measures 23,491 mm³, 24.7% above the reference mean. With a Z-score of 2.10 (98.2th percentile), this represents significant enlargement; middle temporal gyrus volume measures 23,943 mm³, 12.2% above the reference mean. With a Z-score of 1.10 (86.4th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (Z-score 1.41), but hippocampal volume is normal (Z-score -0.08), and other regions show mild to significant enlargement. Cognitive scores (MMSE 28, MoCA 24) are borderline for MCI but not dementia. No APOE4 allele is present, reducing Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
