  "img_finding": "Image findings: ventricular volume measures 21,556 mm³, 3.5% below the reference mean. With a Z-score of -0.09 (46.5th percentile), this represents normal volume ; hippocampal volume measures 8,758 mm³, 14.0% above the reference mean. With a Z-score of 1.57 (94.2th percentile), this represents moderate enlargement; whole brain volume measures 1,109,650 mm³, 7.8% above the reference mean. With a Z-score of 0.97 (83.5th percentile), this represents normal volume ; entorhinal cortex volume measures 6,049 mm³, 55.4% above the reference mean. With a Z-score of 4.29 (100.0th percentile), this represents profound enlargement; fusiform gyrus volume measures 22,050 mm³, 21.1% above the reference mean. With a Z-score of 2.37 (99.1th percentile), this represents significant enlargement; middle temporal gyrus volume measures 20,662 mm³, 0.7% above the reference mean. With a Z-score of 0.06 (52.5th percentile), this represents normal volume . ",
  "text_data": "Age is 69.7 years. Gender is Female. Education: 14 years. MMSE: 30.0. MoCA: 29.0. Logical Memory: 14.0. APOEε4 alleles: 0.0. Biomarker levels: Flobetaben (FBB): 1.07 SUVR (normal ). ",

  "gpt_diagnosis": "Reasoning: The brain volume data shows significant enlargement in key regions (hippocampus, entorhinal cortex, fusiform gyrus) well above reference means, while other regions are normal or slightly above average. Cognitive scores (MMSE 30, MoCA 29) are intact, and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
