  "img_finding": "Image findings: hippocampal volume measures 7,494 mm³, 5.3% above the reference mean. With a Z-score of 0.49 (68.8th percentile), this represents normal volume ; whole brain volume measures 1,072,520 mm³, 10.0% above the reference mean. With a Z-score of 1.26 (89.7th percentile), this represents mild enlargement. ",
  "text_data": "Age is 77.3 years. Gender is Female. Education: 15 years. MMSE: 29.0. MoCA: 26.0. Logical Memory: 9.0. APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.01 SUVR (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal and whole brain volumes are above the reference mean, indicating no significant atrophy. Cognitive scores (MMSE 29, MoCA 26) are within normal limits for age, and amyloid PET (AV45) is normal. The presence of one APOE4 allele does not override the lack of clinical or biomarker evidence of impairment.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
