  "img_finding": "Image findings: ventricular volume measures 41,204 mm³, 46.8% above the reference mean. With a Z-score of 1.07 (85.8th percentile), this represents mild enlargement; hippocampal volume measures 7,233 mm³, 1.7% above the reference mean. With a Z-score of 0.15 (56.1th percentile), this represents normal volume ; whole brain volume measures 987,886 mm³, 1.4% above the reference mean. With a Z-score of 0.17 (56.8th percentile), this represents normal volume . ",
  "text_data": "Age is 76.3 years. Gender is Female. Education: 11 years. MMSE: 28.0. MoCA: 27.0. Laboratory findings: Hemoglobin: 11.40 (significant reduced); Alkaline Phosphatase: 125.00 (significant elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The ventricular volume shows mild enlargement (Z-score 1.07), but hippocampal and whole brain volumes are within normal ranges (Z-scores 0.15 and 0.17, respectively). Cognitive scores (MMSE 28, MoCA 27) are intact, and there is no APOE4 genetic risk.  \n\n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **High**",
