Biomarker levels: Florbetapir (AV45): 1.32 SUVR (moderate elevated); Amyloid beta: 934.10 pg/mL (normal ); Total tau: 327.90 pg/mL (mild elevated); Phosphorylated tau: 30.99 pg/mL (mild elevated). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows normal Aβ levels but mild elevations in T-tau and P-tau, along with moderate AV45 (amyloid PET) elevation, suggesting possible tau pathology despite normal amyloid. Cognitive scores (MMSE 25, MoCA 19) indicate mild impairment, but not severe enough for dementia.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (due to conflicting biomarkers—normal Aβ but elevated tau and AV45)",
