  "img_finding": "Image findings: ventricular volume measures 28,738 mm³, 28.7% above the reference mean. With a Z-score of 0.72 (76.3th percentile), this represents normal volume ; whole brain volume measures 1,122,720 mm³, 9.1% above the reference mean. With a Z-score of 1.13 (87.1th percentile), this represents mild enlargement. ",
  "text_data": "Age is 66.5 years. Gender is Female. Education: 18 years. Handedness: Right. Race: White. Medical history: Psychiatric; Musculoskeletal. MMSE: 30.0. Logical Memory: 8.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, and the whole brain volume is mildly enlarged, which does not suggest atrophy. The MMSE score of 30/30 is optimal, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
