  "img_finding": "Image findings: ventricular volume measures 49,266 mm³, 4.8% above the reference mean. With a Z-score of 0.14 (55.5th percentile), this represents normal volume ; whole brain volume measures 946,080 mm³, 8.1% below the reference mean. With a Z-score of -1.06 (14.5th percentile), this represents mild atrophy. ",
  "text_data": "Age is 85.1 years. Gender is Male. Education: 16 years. MMSE: 30.0. Logical Memory: 15.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.06, 14.5th percentile) but normal ventricular volume. Despite being 85 years old, cognitive performance (MMSE 30) is intact, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy could suggest early changes, but preserved MMSE and lack of APOE4 support normal cognition)",
