  "img_finding": "Image findings: hippocampal volume measures 7,972 mm³, 5.5% above the reference mean. With a Z-score of 0.53 (70.3th percentile), this represents normal volume . ",
  "text_data": "Age is 73.7 years. Gender is Male. Education: 12 years. MMSE: 21.0. Logical Memory: 8.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.95 SUVR (mild reduced). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is within the normal range (Z-score 0.53, 70.3th percentile), but the MMSE score of 21 suggests cognitive impairment. The absence of APOE4 and only mild amyloid burden (AV45) reduces the likelihood of Alzheimer's pathology as the primary cause.  \n**Diagnosis:** MCI (likely non-amnestic or non-AD etiology)  \n**Confidence:** Medium (due to discordance between structural imaging and cognitive performance, with unclear etiology)",
