  "img_finding": "Image findings: ventricular volume measures 22,274 mm³, 39.7% below the reference mean. With a Z-score of -1.07 (14.2th percentile), this represents mild atrophy; whole brain volume measures 1,040,250 mm³, 12.1% above the reference mean. With a Z-score of 1.45 (92.6th percentile), this represents mild enlargement. ",
  "text_data": "Age is 80.0 years. Gender is Female. Education: 19 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal. MMSE: 29.0. Logical Memory: 3.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows mild atrophy (Z-score -1.07), but whole brain volume is mildly enlarged (Z-score +1.45). MMSE is normal (29/30), and there is no APOE4 risk allele. The atrophy is not severe enough to suggest significant neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy is present but not clinically significant given normal MMSE and lack of APOE4)",
