  "img_finding": "Image findings: ventricular volume measures 13,836 mm³, 50.7% below the reference mean. With a Z-score of -1.16 (12.3th percentile), this represents mild atrophy; hippocampal volume measures 6,944 mm³, 2.4% below the reference mean. With a Z-score of -0.22 (41.3th percentile), this represents normal volume ; whole brain volume measures 909,860 mm³, 6.6% below the reference mean. With a Z-score of -0.84 (20.1th percentile), this represents normal volume . ",
  "text_data": "Age is 73.3 years. Gender is Female. Education: 12 years. MMSE: 30.0. MoCA: 23.0. Logical Memory: 6.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The data shows mild ventricular atrophy but normal hippocampal and whole brain volumes. The MMSE score is normal (30/30), but the MoCA score (23/30) suggests mild cognitive impairment, particularly given the presence of two APOE4 alleles, which increases Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA is borderline, and structural changes are mild but not definitive for dementia.)",
