  "img_finding": "Image findings: ventricular volume measures 34,945 mm³, 16.4% above the reference mean. With a Z-score of 0.39 (65.1th percentile), this represents normal volume ; whole brain volume measures 1,106,230 mm³, 2.5% below the reference mean. With a Z-score of -0.35 (36.2th percentile), this represents normal volume . ",
  "text_data": "Age is 63.1 years. Gender is Male. Education: 12 years. Handedness: Left. Race: White. Medical history: Psychiatric; Cardiovascular; Dermatologic-Connective Tissue; Musculoskeletal; Endocrine-Metabolic; Hematopoietic-Lymphatic; Smoking. MMSE: 25.0. Logical Memory: 3.0. APOEε4 alleles: 0.0. Biomarker levels: Pittsburgh compound B: 1.36 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.39), and whole brain volume is slightly below the reference mean but also normal (Z-score -0.35). The MMSE score of 25 is borderline but not definitively indicative of cognitive impairment, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MMSE but otherwise normal imaging and genetic markers)",
