  "img_finding": "Image findings: hippocampal volume measures 9,540 mm³, 18.8% above the reference mean. With a Z-score of 1.88 (97.0th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 63.6 years. Gender is Male. Education: 14 years. MMSE: 21.0. MoCA: 12.0. Logical Memory: 1.0. APOEε4 alleles: 0.0. Biomarker levels: Amyloid beta: 1253.00 pg/mL (normal ); Total tau: 164.70 pg/mL (normal ); Phosphorylated tau: 13.72 pg/mL (mild reduced). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is significantly above the reference mean, which is unusual for Alzheimer's disease (AD) as AD typically involves hippocampal atrophy. The MMSE and MoCA scores indicate cognitive impairment, but the normal Aβ and tau levels, along with the absence of APOE4, suggest that AD is unlikely. The cognitive impairment may be due to another cause.  \nDiagnosis: MCI  \nConfidence: Medium",
