  "img_finding": "Image findings: ventricular volume measures 63,957 mm³, 36.0% above the reference mean. With a Z-score of 1.05 (85.2th percentile), this represents mild enlargement; whole brain volume measures 1,066,140 mm³, 3.6% above the reference mean. With a Z-score of 0.47 (68.1th percentile), this represents normal volume . ",
  "text_data": "Age is 80.3 years. Gender is Male. Education: 20 years. MMSE: 28.0. MoCA: 27.0. Logical Memory: 8.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is mildly enlarged (36% above reference mean), but whole brain volume is normal (3.6% above reference mean). Cognitive scores (MMSE 28, MoCA 27) are within normal limits for age, and APOE4 carrier status alone does not confirm pathology.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (mild ventricular enlargement could be age-related, but cognitive performance remains intact)",
