Biomarker levels: Florbetapir (AV45): 1.00 SUVR (normal ); Amyloid beta: 1541.00 pg/mL (mild elevated); Total tau: 187.40 pg/mL (normal ); Phosphorylated tau: 16.81 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is above the reference mean, cognitive scores (MMSE, MoCA) are within normal range, and biomarkers (Aβ mildly elevated but T-tau/P-tau normal) do not strongly suggest Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mildly elevated Aβ, though other markers are reassuring)",
