  "img_finding": "Image findings: ventricular volume measures 10,076 mm³, 54.9% below the reference mean. With a Z-score of -1.37 (8.5th percentile), this represents mild atrophy; whole brain volume measures 944,687 mm³, 8.2% below the reference mean. With a Z-score of -1.02 (15.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 65.0 years. Gender is Female. Education: 12 years. MMSE: 25.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain imaging shows mild atrophy in both ventricular and whole brain volumes, with Z-scores indicating below-average volumes for age. The MMSE score of 25 is borderline (normal range typically 24-30), and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **Mild Cognitive Impairment (MCI)**  \nConfidence: **Medium** (Atrophy and genetic risk suggest MCI, but MMSE is near-normal and clinical correlation is needed.)",
