  "img_finding": "Image findings: ventricular volume measures 55,093 mm³, 17.2% above the reference mean. With a Z-score of 0.50 (69.1th percentile), this represents normal volume ; whole brain volume measures 901,860 mm³, 12.4% below the reference mean. With a Z-score of -1.62 (5.3th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 81.0 years. Gender is Male. Education: 20 years. MMSE: 30.0. Logical Memory: 18.0. APOEε4 alleles: 0.0. Biomarker levels: Total tau: 363.90 pg/mL (moderate elevated); Phosphorylated tau: 31.03 pg/mL (mild elevated). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.62, 5.3th percentile) but normal ventricular volume. Despite elevated T-tau and P-tau, cognitive function (MMSE 30) is intact, and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (Biomarkers suggest early pathology, but cognition remains unaffected.)",
