Biomarker levels: Florbetapir (AV45): 1.40 SUVR (significant elevated); Amyloid beta: 356.90 pg/mL (moderate reduced); Total tau: 282.10 pg/mL (normal ); Phosphorylated tau: 27.77 pg/mL (normal ). ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows cognitive impairment (MMSE 23, MoCA 20) with elevated AV45 (amyloid PET) and moderately reduced Aβ, suggesting amyloid pathology. However, normal T-tau and P-tau levels argue against significant neurodegeneration.  \nDiagnosis: **MCI (likely due to Alzheimer's pathology)**  \nConfidence: **Medium** (cognitive scores and amyloid markers support MCI, but tau normality introduces some uncertainty about progression).",
