  "img_finding": "Image findings: ventricular volume measures 19,672 mm³, 48.9% below the reference mean. With a Z-score of -1.17 (12.1th percentile), this represents mild atrophy; whole brain volume measures 1,231,190 mm³, 14.1% above the reference mean. With a Z-score of 1.83 (96.6th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 73.1 years. Gender is Male. Education: 16 years. Handedness: Right. Race: White. Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Hepatic; Musculoskeletal; Allergies or Drug Sensitivities; Smoking; Major Surgical Procedures. MMSE: 30.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy, but the whole brain volume is significantly above the reference mean, suggesting no substantial neurodegeneration. The MMSE score of 30 is normal, and the absence of APOE4 alleles reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
