  "img_finding": "Image findings: ventricular volume measures 52,282 mm³, 35.7% above the reference mean. With a Z-score of 0.86 (80.4th percentile), this represents normal volume ; whole brain volume measures 979,240 mm³, 9.3% below the reference mean. With a Z-score of -1.20 (11.4th percentile), this represents mild atrophy. ",
  "text_data": "Age is 74.8 years. Gender is Male. Education: 12 years. MMSE: 24.0. MoCA: 19.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The patient shows mild whole brain atrophy (Z-score -1.20, 11.4th percentile) and normal ventricular volume. Cognitive testing (MMSE 24, MoCA 19) indicates mild impairment, consistent with MCI. APOE4 carrier status increases Alzheimer's risk.  \n\n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium (cognitive scores suggest MCI, but clinical correlation is needed to rule out other causes)",
