With a Z-score of -0.77 (21.9th percentile), this represents normal volume ; whole brain volume measures 1,009,610 mm³, 6.5% below the reference mean. With a Z-score of -0.84 (20.1th percentile), this represents normal volume . ",

Biomarker levels: Florbetapir (AV45): 1.27 SUVR (moderate elevated); Amyloid beta: 1113.00 pg/mL (normal ); Total tau: 290.10 pg/mL (normal ); Phosphorylated tau: 28.24 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular and whole brain) are within normal ranges, and the MMSE score of 30 indicates no cognitive impairment. However, the MoCA score of 25 suggests mild cognitive difficulties, but biomarkers (Aβ, T-tau, P-tau) are normal, and AV45 (amyloid PET) shows only moderate elevation, which is not strongly indicative of Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to the discrepancy between MMSE and MoCA, but normal biomarkers and imaging suggest no significant pathology)",
