  "img_finding": "Image findings: ventricular volume measures 30,601 mm³, 1.9% above the reference mean. With a Z-score of 0.05 (51.8th percentile), this represents normal volume ; whole brain volume measures 997,399 mm³, 12.1% below the reference mean. With a Z-score of -1.71 (4.4th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 64.6 years. Gender is Male. Education: 14 years. MMSE: 25.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. Biomarker levels: Amyloid beta: 529.20 pg/mL (mild reduced); Total tau: 363.40 pg/mL (moderate elevated); Phosphorylated tau: 40.69 pg/mL (significant elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The patient shows moderate whole brain atrophy (Z-score -1.71, 4.4th percentile) with normal ventricular volume. Biomarkers indicate amyloid pathology (Aβ mildly reduced) and significant tauopathy (elevated T-tau and P-tau). The MMSE score of 25 suggests mild cognitive impairment.  \n**Diagnosis:** MCI (likely due to Alzheimer’s pathology)  \n**Confidence:** Medium (clinical correlation needed for progression rate and functional impact)",
