  "img_finding": "Image findings: ventricular volume measures 38,707 mm³, 0.5% above the reference mean. With a Z-score of 0.01 (50.5th percentile), this represents normal volume ; whole brain volume measures 1,127,120 mm³, 4.4% above the reference mean. With a Z-score of 0.57 (71.7th percentile), this represents normal volume . ",
  "text_data": "Age is 72.9 years. Gender is Male. Education: 19 years. MMSE: 26.0. Laboratory findings: Alkaline Phosphatase: 203.00 (profound elevated). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 26 is just below the typical cutoff for mild cognitive impairment (27-30 is normal). The presence of one APOE4 allele increases Alzheimer's risk but does not confirm impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MMSE is borderline, but structural imaging is normal)",
