  "img_finding": "Image findings: ventricular volume measures 60,289 mm³, 63.1% above the reference mean. With a Z-score of 1.70 (95.6th percentile), this represents moderate enlargement; whole brain volume measures 830,887 mm³, 10.5% below the reference mean. With a Z-score of -1.26 (10.4th percentile), this represents mild atrophy. ",
  "text_data": "Age is 84.0 years. Gender is Female. Education: 12 years. MMSE: 27.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 643.40 pg/mL (mild reduced); Total tau: 321.30 pg/mL (mild elevated); Phosphorylated tau: 33.87 pg/mL (moderate elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The data shows moderate ventricular enlargement and mild whole brain atrophy, which are consistent with neurodegenerative changes. The MMSE score of 27 is within the normal range, but the presence of mildly reduced Aβ and moderately elevated P-tau suggests early Alzheimer's pathology.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to normal MMSE but biomarker evidence of Alzheimer's pathology)",
