  "img_finding": "Image findings: ventricular volume measures 29,613 mm³, 18.4% above the reference mean. With a Z-score of 0.24 (59.6th percentile), this represents normal volume ; hippocampal volume measures 8,957 mm³.; whole brain volume measures 1,283,090 mm³, 7.6% above the reference mean. With a Z-score of 1.41 (92.1th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,965 mm³, 1.0% below the reference mean. With a Z-score of -0.08 (46.7th percentile), this represents normal volume ; fusiform gyrus volume measures 25,930 mm³, 24.4% above the reference mean. With a Z-score of 3.71 (100.0th percentile), this represents profound enlargement; middle temporal gyrus volume measures 26,195 mm³.. ",
  "text_data": "Age is 59.9 years. Gender is Male. Education: 19 years. MMSE: 30.0. MoCA: 26.0. Logical Memory: 15.0. Laboratory findings: . APOEε4 alleles: 1.0. Biomarker levels: Florbetapir (AV45): 1.06 SUVR (normal ); Amyloid beta: 1327.00 pg/mL (normal ); Total tau: 198.70 pg/mL (normal ); Phosphorylated tau: 18.65 pg/mL (normal ). ",

  "gpt_diagnosis": "Reasoning: The brain volume measures show normal or enlarged volumes in most regions, with no significant atrophy. Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, and cognitive scores (MMSE 30, MoCA 26) are within normal ranges despite a slightly lower MoCA. APOE4 carrier status is present but not currently associated with pathological changes.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MoCA is borderline, but other markers strongly support normal cognition)",
