  "img_finding": "Image findings: ventricular volume measures 31,599 mm³, 5.2% above the reference mean. With a Z-score of 0.12 (55.0th percentile), this represents normal volume ; whole brain volume measures 994,542 mm³, 12.3% below the reference mean. With a Z-score of -1.75 (4.0th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 65.1 years. Gender is Male. Education: 14 years. MMSE: 24.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.75, 4th percentile) with normal ventricular volume, which is concerning for neurodegeneration. The MMSE score of 24 is borderline, and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **MCI (likely prodromal Alzheimer's)**  \nConfidence: **Medium** (clinical correlation and biomarker data would strengthen certainty)",
