  "img_finding": "Image findings: ventricular volume measures 66,505 mm³, 41.5% above the reference mean. With a Z-score of 1.20 (88.6th percentile), this represents mild enlargement; hippocampal volume measures 5,277 mm³, 24.3% below the reference mean. With a Z-score of -2.10 (1.8th percentile), this represents significant atrophy; whole brain volume measures 1,011,990 mm³, 1.7% below the reference mean. With a Z-score of -0.22 (41.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The data shows significant hippocampal atrophy (Z-score -2.10, 1.8th percentile) and mild ventricular enlargement, which are strong indicators of neurodegeneration. The MMSE score of 27 is within normal limits, but the MoCA score of 20 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces but does not eliminate Alzheimer's risk.  \n\nDiagnosis: MCI  \nConfidence: Medium",
