  "img_finding": "Image findings: ventricular volume measures 38,540 mm³, 37.3% above the reference mean. With a Z-score of 0.85 (80.4th percentile), this represents normal volume ; whole brain volume measures 1,052,020 mm³, 7.9% above the reference mean. With a Z-score of 1.00 (84.1th percentile), this represents normal volume . ",
  "text_data": "Age is 71.9 years. Gender is Female. Education: 16 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Musculoskeletal; Gastrointestinal; Major Surgical Procedures. MMSE: 29.0. Logical Memory: 7.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges (Z-scores close to 0, percentiles in the 80s), and the MMSE score of 29 is well within the normal range (≥26). The presence of one APOE4 allele increases Alzheimer's risk but does not alone indicate cognitive impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
