  "img_finding": "Image findings: hippocampal volume measures 7,616 mm³, 5.1% below the reference mean. With a Z-score of -0.51 (30.4th percentile), this represents normal volume . ",
  "text_data": "Age is 68.0 years. Gender is Male. Education: 16 years. MMSE: 29.0. MoCA: 22.0. Logical Memory: 9.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.51). The MMSE score is normal (29/30), but the MoCA score (22/30) suggests mild cognitive impairment, particularly in executive function or attention. No APOE4 allele reduces genetic risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA indicates possible impairment, but hippocampal volume and MMSE are normal)",
