  "img_finding": "Image findings: ventricular volume measures 25,934 mm³, 39.3% above the reference mean. With a Z-score of 1.12 (86.9th percentile), this represents mild enlargement; whole brain volume measures 918,783 mm³, 11.7% below the reference mean. With a Z-score of -1.40 (8.0th percentile), this represents mild atrophy. ",
  "text_data": "Age is 57.1 years. Gender is Female. Education: 18 years. MMSE: 28.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. Biomarker levels: Pittsburgh compound B: 2.26 SUVR (moderate elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The data shows mild ventricular enlargement and mild whole brain atrophy, which are structural changes often seen in neurodegenerative conditions. However, the MMSE score of 28 is within the normal range (≥26), and there is no clear cognitive impairment reported.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (structural changes are present, but cognitive performance remains intact)",
