  "img_finding": "Image findings: hippocampal volume measures 8,619 mm³, 14.0% above the reference mean. With a Z-score of 1.37 (91.4th percentile), this represents mild enlargement. ",
  "text_data": "Age is 73.8 years. Gender is Male. Education: 17 years. MMSE: 30.0. MoCA: 26.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.95 SUVR (mild reduced). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (14.0% above mean, Z-score 1.37), which is atypical for Alzheimer's but not necessarily pathological. Cognitive scores (MMSE 30, MoCA 26) are within normal limits, and there is no APOE4 risk allele. AV45 (amyloid PET) shows mild reduction, which may suggest lower amyloid burden.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (hippocampal enlargement is unusual but cognitive performance and lack of genetic risk support normal status)",
