  "img_finding": "Image findings: ventricular volume measures 17,207 mm³, 38.7% below the reference mean. With a Z-score of -0.89 (18.8th percentile), this represents normal volume ; hippocampal volume measures 8,175 mm³, 14.9% above the reference mean. With a Z-score of 1.37 (91.4th percentile), this represents mild enlargement; whole brain volume measures 1,148,170 mm³, 17.8% above the reference mean. With a Z-score of 2.24 (98.7th percentile), this represents significant enlargement; entorhinal cortex volume measures 4,473 mm³, 21.8% above the reference mean. With a Z-score of 1.34 (90.9th percentile), this represents mild enlargement; fusiform gyrus volume measures 22,535 mm³, 32.5% above the reference mean. With a Z-score of 2.95 (99.8th percentile), this represents significant enlargement; middle temporal gyrus volume measures 21,954 mm³, 14.5% above the reference mean. With a Z-score of 1.26 (89.6th percentile), this represents mild enlargement. ",
  "text_data": "Age is 70.7 years. Gender is Female. Education: 18 years. MMSE: 30.0. MoCA: 30.0. Logical Memory: 15.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.00 SUVR (normal ). ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements show significant enlargement in whole brain, fusiform gyrus, and mild enlargement in hippocampal, entorhinal cortex, and middle temporal gyrus volumes, with normal ventricular volume. Cognitive scores (MMSE and MoCA) are at maximum, and amyloid PET (AV45) is normal. No APOE4 alleles are present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
