Biomarker levels: Florbetapir (AV45): 1.17 SUVR (normal ); Amyloid beta: 662.40 pg/mL (normal ); Total tau: 426.40 pg/mL (significant elevated); Phosphorylated tau: 42.25 pg/mL (significant elevated).

  "gpt_diagnosis": "Reasoning: The hippocampal volume (9,385 mm³) is within normal range for a 55-year-old male. MMSE is normal (30/30), but MoCA (24/30) suggests mild cognitive impairment. Biomarkers show elevated T-tau and P-tau (indicative of neurodegeneration) but normal Aβ and AV45 (no amyloid pathology), which is atypical for Alzheimer's but may suggest another neurodegenerative process.  \nDiagnosis: MCI  \nConfidence: Medium (elevated tau is concerning, but normal amyloid and hippocampal volume make Alzheimer's less likely)",
