  "img_finding": "Image findings: ventricular volume measures 53,149 mm³, 13.0% above the reference mean. With a Z-score of 0.38 (64.8th percentile), this represents normal volume ; whole brain volume measures 968,965 mm³, 5.8% below the reference mean. With a Z-score of -0.77 (22.2th percentile), this represents normal volume . ",
  "text_data": "Age is 80.6 years. Gender is Male. Education: 18 years. Handedness: Right. Race: White. Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Endocrine-Metabolic; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 26.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.38), while whole brain volume is slightly below the reference mean but also within normal limits (Z-score -0.77). The MMSE score of 26 is borderline but does not strongly indicate cognitive impairment, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE and age-related volume changes, but no strong indicators of impairment)",
