  "img_finding": "Image findings: hippocampal volume measures 6,071 mm³, 12.9% below the reference mean. With a Z-score of -1.11 (13.3th percentile), this represents mild atrophy. ",

Biomarker levels: Florbetapir (AV45): 1.03 SUVR (normal ); Amyloid beta: 1475.00 pg/mL (mild elevated); Total tau: 178.90 pg/mL (normal ); Phosphorylated tau: 15.70 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume shows mild atrophy (12.9% below mean, Z-score -1.11), but cognitive scores (MMSE 30, MoCA 29) are intact, and biomarkers (Aβ mildly elevated but tau/AV45 normal) do not strongly support Alzheimer’s pathology.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (mild atrophy could suggest early risk, but cognitive performance and most biomarkers are normal)",
