  "img_finding": "Image findings: hippocampal volume measures 8,502 mm³, 10.6% above the reference mean. With a Z-score of 1.19 (88.4th percentile), this represents mild enlargement. ",
  "text_data": "Age is 62.0 years. Gender is Female. Education: 20 years. MMSE: 30.0. MoCA: 29.0. Logical Memory: 14.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (10.6% above mean, Z-score 1.19), which is atypical for Alzheimer's but not necessarily pathological. Cognitive scores (MMSE 30, MoCA 29) are intact, and while APOE4 homozygosity increases risk, there are no current cognitive deficits.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (due to conflicting markers—hippocampal enlargement and APOE4 risk—but strong cognitive performance)",
