  "img_finding": "Image findings: ventricular volume measures 27,696 mm³, 24.0% above the reference mean. With a Z-score of 0.60 (72.6th percentile), this represents normal volume ; whole brain volume measures 1,178,300 mm³, 14.5% above the reference mean. With a Z-score of 1.80 (96.4th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 68.5 years. Gender is Female. Education: 18 years. MMSE: 30.0. Logical Memory: 16.0. Laboratory findings: Alkaline Phosphatase: 113.00 (significant elevated); Cholesterol (High Performance): 279.00 (significant elevated); GGT: 39.00 (significant elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits (Z-score 0.60), and the whole brain volume is moderately enlarged (Z-score 1.80), which is atypical for Alzheimer's. The MMSE score of 30 is perfect, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
