  "img_finding": "Image findings: hippocampal volume measures 8,108 mm³, 5.5% above the reference mean. With a Z-score of 0.62 (73.2th percentile), this represents normal volume . ",
  "text_data": "Age is 65.2 years. Gender is Female. Education: 18 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Cardiovascular; Dermatologic-Connective Tissue; Musculoskeletal; Endocrine-Metabolic; Gastrointestinal; Hematopoietic-Lymphatic; Renal-Genitourinary; Allergies or Drug Sensitivities; Malignancy; Major Surgical Procedures. MMSE: 28.0. MoCA: 27.0. Logical Memory: 14.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 1.08 SUVR (normal ); Amyloid beta: 1386.00 pg/mL (normal ); Total tau: 119.70 pg/mL (moderate reduced); Phosphorylated tau: 11.81 pg/mL (mild reduced). ",

  "gpt_diagnosis": "Reasoning: The hippocampal volume is above the reference mean, and cognitive scores (MMSE 28, MoCA 27) are within normal ranges. Biomarkers (Aβ normal, AV45 normal) do not indicate amyloid pathology, while tau levels are reduced, which is atypical for Alzheimer's but not concerning for neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
