  "img_finding": "Image findings: ventricular volume measures 67,972 mm³, 76.5% above the reference mean. With a Z-score of 1.83 (96.7th percentile), this represents moderate enlargement; hippocampal volume measures 6,124 mm³, 19.0% below the reference mean. With a Z-score of -1.85 (3.2th percentile), this represents moderate atrophy; whole brain volume measures 1,038,340 mm³, 3.8% below the reference mean. With a Z-score of -0.49 (31.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,025 mm³, 26.2% below the reference mean. With a Z-score of -1.78 (3.8th percentile), this represents moderate atrophy; fusiform gyrus volume measures 14,917 mm³, 20.8% below the reference mean. With a Z-score of -1.77 (3.8th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 13,390 mm³, 37.3% below the reference mean. With a Z-score of -3.35 (0.0th percentile), this represents profound atrophy. ",
  "text_data": "Age is 73.0 years. Gender is Male. Education: 16 years. MMSE: 23.0. Logical Memory: 2.0. Laboratory findings: Eosinophils: 0.33 (significant elevated); Serum Glucose: 71.00 (significant reduced); Alkaline Phosphatase: 113.00 (significant elevated). APOEε4 alleles: 2.0. ",

  "gpt_diagnosis": "**Reasoning:** The patient exhibits significant atrophy in key Alzheimer’s-related regions (hippocampus, entorhinal cortex, fusiform gyrus, and profound atrophy in the middle temporal gyrus), alongside ventricular enlargement. The MMSE score of 23 suggests cognitive impairment, and the presence of two APOE4 alleles increases Alzheimer’s risk.  \n\n**Diagnosis:** **Dementia (likely Alzheimer’s disease)**  \n**Confidence:** **High**",
