  "img_finding": "Image findings: hippocampal volume measures 7,339 mm³, 5.3% above the reference mean. With a Z-score of 0.46 (67.7th percentile), this represents normal volume . ",
  "text_data": "Age is 86.3 years. Gender is Male. Education: 12 years. MMSE: 24.0. MoCA: 19.0. Logical Memory: 6.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is within the normal range (Z-score 0.46), but cognitive scores (MMSE 24, MoCA 19) suggest mild impairment, particularly on the MoCA, which is more sensitive to early cognitive decline. The presence of one APOE4 allele increases Alzheimer's risk but is not definitive.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (cognitive scores indicate impairment, but hippocampal volume is preserved, and APOE4 status alone is not diagnostic)",
