  "img_finding": "Image findings: hippocampal volume measures 7,722 mm³, 8.5% above the reference mean. With a Z-score of 0.78 (78.3th percentile), this represents normal volume ; whole brain volume measures 1,128,310 mm³, 15.8% above the reference mean. With a Z-score of 1.98 (97.6th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 73.0 years. Gender is Female. Education: 16 years. MMSE: 27.0. MoCA: 24.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** Hippocampal and whole brain volumes are above the reference mean, with no atrophy suggestive of neurodegeneration. Cognitive scores (MMSE 27, MoCA 24) are within normal limits for age, and APOE4 heterozygosity alone does not indicate pathology.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
