  "img_finding": "Image findings: ventricular volume measures 22,168 mm³, 42.4% below the reference mean. With a Z-score of -1.02 (15.5th percentile), this represents mild atrophy; whole brain volume measures 1,033,650 mm³, 4.2% below the reference mean. With a Z-score of -0.55 (29.1th percentile), this represents normal volume . ",
  "text_data": "Age is 78.3 years. Gender is Male. Education: 14 years. Handedness: Left. Race: Asian. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Renal-Genitourinary; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 29.0. Logical Memory: 10.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy, but whole brain volume is within normal limits. The MMSE score of 29 is normal, and while APOE4 homozygosity (2 alleles) is a strong genetic risk factor for Alzheimer's, there is no significant cognitive impairment currently present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to APOE4 risk but lack of clinical or significant structural impairment)",
