  "img_finding": "Image findings: hippocampal volume measures 7,018 mm³, 12.6% below the reference mean. With a Z-score of -1.26 (10.4th percentile), this represents mild atrophy. ",
  "text_data": "Age is 68.5 years. Gender is Male. Education: 17 years. MMSE: 30.0. MoCA: 23.0. Logical Memory: 11.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.03 SUVR (normal ). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume shows mild atrophy (12.6% below mean, Z-score -1.26), but the MMSE is normal (30/30), while the MoCA (23/30) suggests mild cognitive impairment. No APOE4 or amyloid pathology (AV45 normal) reduces Alzheimer’s likelihood.  \n**Diagnosis:** **MCI** (due to MoCA score and hippocampal atrophy, but preserved MMSE and no amyloid burden).  \n**Confidence:** **Medium** (conflicting MMSE/MoCA, but structural changes support MCI).",
