Biomarker levels: Florbetapir (AV45): 1.56 SUVR (profound elevated); Amyloid beta: 711.30 pg/mL (normal ); Total tau: 209.80 pg/mL (normal ); Phosphorylated tau: 20.54 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The patient shows normal biomarkers (Aβ, T-tau, P-tau) but has a profoundly elevated AV45 (amyloid PET), suggesting possible amyloid deposition despite normal CSF markers. Cognitive scores (MMSE 25, MoCA 21) indicate mild cognitive impairment, but the discrepancy between AV45 and CSF Aβ warrants caution.  \nDiagnosis: MCI  \nConfidence: Medium",
