  "img_finding": "Image findings: ventricular volume measures 37,976 mm³, 2.7% above the reference mean. With a Z-score of 0.07 (52.9th percentile), this represents normal volume ; whole brain volume measures 860,585 mm³, 7.3% below the reference mean. With a Z-score of -0.87 (19.1th percentile), this represents normal volume . ",
  "text_data": "Age is 88.6 years. Gender is Female. Education: 20 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Endocrine-Metabolic. MMSE: 30.0. Logical Memory: 16.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.07), while the whole brain volume is slightly below the reference mean but also within normal range (Z-score -0.87). The MMSE score of 30 is perfect, and there is no APOE4 allele, which reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
