  "img_finding": "Image findings: ventricular volume measures 23,629 mm³, 5.8% above the reference mean. With a Z-score of 0.14 (55.8th percentile), this represents normal volume ; whole brain volume measures 883,690 mm³, 14.1% below the reference mean. With a Z-score of -1.76 (3.9th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 69.1 years. Gender is Female. Education: 12 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Smoking; Major Surgical Procedures. MMSE: 25.0. Logical Memory: 2.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.76, 3.9th percentile) but normal ventricular volume. The MMSE score of 25 is borderline, and the presence of two APOE4 alleles increases Alzheimer's risk. These findings suggest cognitive impairment but not severe dementia.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (MMSE is borderline, and brain atrophy supports impairment, but clinical correlation is needed for definitive diagnosis)",
