  "img_finding": "Image findings: ventricular volume measures 36,214 mm³, 29.0% above the reference mean. With a Z-score of 0.66 (74.7th percentile), this represents normal volume ; whole brain volume measures 831,120 mm³, 14.7% below the reference mean. With a Z-score of -1.85 (3.2th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 72.6 years. Gender is Female. Education: 12 years. MMSE: 22.0. Logical Memory: 0.0. Laboratory findings: Eosinophils: 0.33 (significant elevated); Eosinophils: 6.00 (significant elevated); Basophils: 0.00 (significant reduced). APOEε4 alleles: 1.0. Biomarker levels: Pittsburgh compound B: 1.71 SUVR (normal ); Amyloid beta: 498.30 pg/mL (mild reduced); Total tau: 373.90 pg/mL (moderate elevated); Phosphorylated tau: 34.70 pg/mL (moderate elevated). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The patient shows moderate whole brain atrophy (Z-score -1.85, 3.2th percentile) and normal ventricular volume. Biomarkers indicate amyloid pathology (Aβ mildly reduced) and neurodegeneration (moderately elevated T-tau and P-tau). The MMSE score of 22 suggests cognitive impairment.  \n**Diagnosis:** Dementia (likely Alzheimer’s disease)  \n**Confidence:** Medium (biomarkers and atrophy support AD, but clinical correlation with other assessments would strengthen confidence)",
