  "img_finding": "Image findings: ventricular volume measures 72,624 mm³, 54.5% above the reference mean. With a Z-score of 1.58 (94.3th percentile), this represents moderate enlargement; whole brain volume measures 848,365 mm³, 17.6% below the reference mean. With a Z-score of -2.30 (1.1th percentile), this represents significant atrophy. ",
  "text_data": "Age is 85.1 years. Gender is Male. Education: 17 years. MMSE: 29.0. MoCA: 23.0. Logical Memory: 13.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The data shows significant whole brain atrophy (Z-score -2.30, 1.1th percentile) and moderate ventricular enlargement (Z-score 1.58, 94.3th percentile), which are structural changes often associated with neurodegenerative processes. Despite the high MMSE score (29.0), the MoCA score (23.0) suggests mild cognitive impairment, and the absence of APOE4 does not rule out neurodegeneration given the pronounced atrophy.  \n\nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (due to conflicting MMSE/MoCA scores but clear structural evidence of neurodegeneration)",
