  "img_finding": "Image findings: hippocampal volume measures 7,055 mm³, 6.7% below the reference mean. With a Z-score of -0.65 (25.8th percentile), this represents normal volume . ",
  "text_data": "Age is 71.4 years. Gender is Male. Education: 20 years. MMSE: 29.0. MoCA: 27.0. Logical Memory: 10.0. APOEε4 alleles: 2.0. Biomarker levels: Florbetapir (AV45): 1.10 SUVR (normal ); Amyloid beta: 413.20 pg/mL (moderate reduced); Total tau: 212.20 pg/mL (normal ); Phosphorylated tau: 18.78 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is slightly below the reference mean but still within the normal range (Z-score -0.65). Cognitive scores (MMSE 29, MoCA 27) are intact, and while Aβ is moderately reduced, tau markers and AV45 are normal, suggesting no significant neurodegenerative pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to moderately reduced Aβ, but otherwise normal biomarkers and cognition)",
