  "img_finding": "Image findings: ventricular volume measures 107,503 mm³, 258.0% above the reference mean. With a Z-score of 6.13 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 5,831 mm³, 27.4% below the reference mean. With a Z-score of -2.73 (0.3th percentile), this represents significant atrophy; whole brain volume measures 1,161,500 mm³, 2.4% above the reference mean. With a Z-score of 0.34 (63.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,071 mm³, 28.0% below the reference mean. With a Z-score of -1.94 (2.6th percentile), this represents moderate atrophy; fusiform gyrus volume measures 19,096 mm³, 4.1% below the reference mean. With a Z-score of -0.34 (36.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,428 mm³, 4.4% below the reference mean. With a Z-score of -0.36 (35.9th percentile), this represents normal volume . ",
  "text_data": "Age is 67.3 years. Gender is Male. Education: 16 years. MMSE: 24.0. MoCA: 17.0. Logical Memory: 0.0. Laboratory findings: Neutrophils: 40.10 (significant reduced); Lymphocytes: 44.80 (significant elevated); Eosinophils: 6.50 (significant elevated); WBC: 3.22 (significant reduced); Neutrophils: 1.29 (significant reduced). APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.21 SUVR (normal ); Amyloid beta: 700.90 pg/mL (normal ); Total tau: 288.50 pg/mL (normal ); Phosphorylated tau: 25.91 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement and significant hippocampal atrophy, which are strong indicators of neurodegeneration. The MMSE and MoCA scores (24 and 17, respectively) suggest cognitive impairment, but the normal Aβ, T-tau, and P-tau levels argue against Alzheimer's pathology.  \nDiagnosis: MCI (likely non-AD etiology, such as hippocampal sclerosis or vascular contributions)  \nConfidence: Medium (cognitive scores and imaging support MCI, but biomarker profile is atypical for AD)",
