  "img_finding": "Image findings: ventricular volume measures 44,104 mm³, 14.5% above the reference mean. With a Z-score of 0.35 (63.6th percentile), this represents normal volume ; whole brain volume measures 1,132,590 mm³, 4.9% above the reference mean. With a Z-score of 0.64 (73.9th percentile), this represents normal volume . ",
  "text_data": "Age is 73.4 years. Gender is Male. Education: 12 years. MMSE: 25.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges, and the MMSE score of 25 is borderline but not strongly indicative of cognitive impairment. The absence of APOE4 reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MMSE is slightly below typical cutoff for normality, but other markers are reassuring)",
