  "img_finding": "Image findings: hippocampal volume measures 7,608 mm³, 17.1% above the reference mean. With a Z-score of 1.37 (91.5th percentile), this represents mild enlargement. ",
  "text_data": "Age is 85.3 years. Gender is Female. Education: 12 years. MMSE: 28.0. MoCA: 26.0. Logical Memory: 8.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.26 SUVR (mild elevated); Amyloid beta: 1074.00 pg/mL (normal ); Total tau: 331.30 pg/mL (mild elevated); Phosphorylated tau: 31.58 pg/mL (mild elevated). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is mildly enlarged (17.1% above mean, Z-score 1.37), which is atypical for Alzheimer's pathology. Cognitive scores (MMSE 28, MoCA 26) are within normal limits, and Aβ is normal, though T-tau, P-tau, and AV45 show mild elevations, suggesting possible non-AD neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting biomarker elevations despite normal cognition and hippocampal enlargement)",
