  "img_finding": "Image findings: hippocampal volume measures 6,189 mm³, 13.0% below the reference mean. With a Z-score of -1.19 (11.6th percentile), this represents mild atrophy. ",
  "text_data": "Age is 74.4 years. Gender is Female. Education: 13 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 15.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (13.0% below reference mean, Z-score -1.19), but cognitive scores are mixed—MMSE is normal (29/30), while MoCA is borderline (24/30, with <26 often indicating impairment). No APOE4 risk allele is present.  \nDiagnosis: **MCI (Mild Cognitive Impairment)**  \nConfidence: **Medium** (Hippocampal atrophy and borderline MoCA suggest MCI, but high MMSE and lack of APOE4 reduce certainty.)",
