  "img_finding": "Image findings: hippocampal volume measures 6,999 mm³, 7.8% above the reference mean. With a Z-score of 0.62 (73.3th percentile), this represents normal volume . ",
  "text_data": "Age is 80.9 years. Gender is Female. Education: 16 years. MMSE: 29.0. MoCA: 26.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.25 SUVR (mild elevated). ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is above the reference mean, indicating no significant atrophy. Cognitive scores (MMSE 29, MoCA 26) are within normal ranges for age, and there is no APOE4 risk allele. Mild AV45 elevation suggests some amyloid deposition but not enough to impair cognition.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
