  "img_finding": "Image findings: hippocampal volume measures 7,497 mm³, 15.4% above the reference mean. With a Z-score of 1.24 (89.2th percentile), this represents mild enlargement. ",
  "text_data": "Age is 84.4 years. Gender is Female. Education: 12 years. MMSE: 29.0. MoCA: 29.0. Logical Memory: 14.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (15.4% above the mean), which is atypical for Alzheimer's but not necessarily pathological. Cognitive scores (MMSE 29, MoCA 29) are intact, and APOE4 status (heterozygous) alone does not indicate impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (hippocampal enlargement is unusual but cognitive performance is strong)",
