  "img_finding": "Image findings: ventricular volume measures 100,399 mm³, 113.5% above the reference mean. With a Z-score of 3.30 (100.0th percentile), this represents profound enlargement; whole brain volume measures 1,143,530 mm³, 11.1% above the reference mean. With a Z-score of 1.46 (92.7th percentile), this represents mild enlargement. ",
  "text_data": "Age is 84.3 years. Gender is Male. Education: 16 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Renal-Genitourinary; Major Surgical Procedures. MMSE: 25.0. Logical Memory: 5.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is significantly enlarged (Z-score 3.30, 100th percentile), which is strongly associated with neurodegeneration, while whole brain volume is mildly enlarged (Z-score 1.46). The MMSE score of 25 is borderline but still within normal limits for age, and the absence of APOE4 reduces genetic risk.  \n**Diagnosis:** Mild Cognitive Impairment (MCI)  \n**Confidence:** Medium (ventricular enlargement suggests neurodegeneration, but MMSE is not severely impaired)",
