  "img_finding": "Image findings: ventricular volume measures 37,938 mm³, 1.5% below the reference mean. With a Z-score of -0.04 (48.6th percentile), this represents normal volume ; whole brain volume measures 918,007 mm³, 15.0% below the reference mean. With a Z-score of -1.94 (2.6th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 77.9 years. Gender is Male. Education: 20 years. Handedness: Unknown. Race: Unknown. MMSE: 27.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.94, 2.6th percentile) but normal ventricular volume. The MMSE score of 27 is within the normal range, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (Brain atrophy is notable, but cognitive performance is preserved, and no genetic risk is present.)",
