  "img_finding": "Image findings: ventricular volume measures 38,697 mm³, 37.9% above the reference mean. With a Z-score of 0.87 (80.7th percentile), this represents normal volume ; whole brain volume measures 956,343 mm³, 1.9% below the reference mean. With a Z-score of -0.24 (40.7th percentile), this represents normal volume . ",
  "text_data": "Age is 76.4 years. Gender is Female. Education: 16 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal; Hematopoietic-Lymphatic; Allergies or Drug Sensitivities; Malignancy; Major Surgical Procedures. MMSE: 30.0. MoCA: 23.0. Logical Memory: 14.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, and the whole brain volume is only slightly below the reference mean, both with normal Z-scores. The MMSE score is perfect (30/30), but the MoCA score (23/30) suggests mild cognitive impairment, though APOE4-negative status lowers Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA indicates possible impairment, but structural brain measures and MMSE are normal; APOE4-negative reduces Alzheimer's likelihood.)",
