  "img_finding": "Image findings: ventricular volume measures 63,337 mm³, 34.7% above the reference mean. With a Z-score of 1.01 (84.3th percentile), this represents mild enlargement; whole brain volume measures 874,158 mm³, 15.1% below the reference mean. With a Z-score of -1.97 (2.4th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 88.6 years. Gender is Male. Education: 16 years. MMSE: 25.0. Laboratory findings: Hematocrit: 33.00 (significant reduced); RBC: 3.70 (significant reduced); Hemoglobin: 10.20 (profound reduced); Triglycerides (GPO): 301.00 (profound elevated). APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The data shows moderate whole brain atrophy and mild ventricular enlargement, which are consistent with neurodegenerative changes. The MMSE score of 25 is borderline for mild cognitive impairment (MCI), and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (Clinical correlation and further cognitive testing would help confirm progression to dementia.)",
