  "img_finding": "Image findings: ventricular volume measures 12,694 mm³, 57.7% below the reference mean. With a Z-score of -1.37 (8.5th percentile), this represents mild atrophy; hippocampal volume measures 9,436 mm³, 17.6% above the reference mean. With a Z-score of 1.75 (96.0th percentile), this represents moderate enlargement; whole brain volume measures 1,211,910 mm³, 6.8% above the reference mean. With a Z-score of 0.97 (83.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,857 mm³, 9.5% below the reference mean. With a Z-score of -0.66 (25.5th percentile), this represents normal volume ; fusiform gyrus volume measures 22,099 mm³, 11.0% above the reference mean. With a Z-score of 0.91 (82.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,908 mm³, 2.2% below the reference mean. With a Z-score of -0.19 (42.7th percentile), this represents normal volume . ",
  "text_data": "Age is 63.4 years. Gender is Male. Education: 16 years. MMSE: 30.0. Logical Memory: 10.0. Laboratory findings: Hematocrit: 53.00 (profound elevated); Hemoglobin: 16.20 (significant elevated); Total Protein: 8.20 (significant elevated); GGT: 71.00 (profound elevated). APOEε4 alleles: 0.0. Biomarker levels: Pittsburgh compound B: 1.13 SUVR (mild reduced). ",

  "gpt_diagnosis": "Reasoning: The data shows mild ventricular atrophy but otherwise normal or above-average volumes in key regions (hippocampus, whole brain, fusiform gyrus). The MMSE score of 30 is intact, and there is no APOE4 risk allele. No significant atrophy is seen in Alzheimer’s-vulnerable regions like the entorhinal cortex or middle temporal gyrus.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
