  "img_finding": "Image findings: ventricular volume measures 41,300 mm³, 47.1% above the reference mean. With a Z-score of 1.08 (86.0th percentile), this represents mild enlargement; whole brain volume measures 961,814 mm³, 1.3% below the reference mean. With a Z-score of -0.17 (43.4th percentile), this represents normal volume . ",
  "text_data": "Age is 70.6 years. Gender is Female. Education: 14 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Renal-Genitourinary; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 23.0. Logical Memory: 2.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is mildly enlarged (47.1% above reference mean, Z-score 1.08), while whole brain volume is within normal limits (Z-score -0.17). The MMSE score of 23 suggests mild cognitive impairment, and the presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MMSE supports MCI, but structural changes are mild and APOE4 alone is not definitive).",
