  "img_finding": "Image findings: ventricular volume measures 12,215 mm³, 59.3% below the reference mean. With a Z-score of -1.41 (7.9th percentile), this represents mild atrophy; hippocampal volume measures 9,405 mm³, 17.2% above the reference mean. With a Z-score of 1.72 (95.7th percentile), this represents moderate enlargement; whole brain volume measures 1,236,740 mm³, 9.0% above the reference mean. With a Z-score of 1.28 (89.9th percentile), this represents mild enlargement. ",
  "text_data": "Age is 64.4 years. Gender is Male. Education: 18 years. MMSE: 28.0. MoCA: 26.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal and whole brain volumes are above the reference mean, suggesting no significant atrophy, while ventricular volume shows mild atrophy. Cognitive scores (MMSE 28, MoCA 26) are within normal limits, and APOE4 status (heterozygous) alone does not confirm pathology.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (due to mild ventricular atrophy, but otherwise normal cognitive and structural findings)",
