  "img_finding": "Image findings: ventricular volume measures 78,326 mm³, 160.9% above the reference mean. With a Z-score of 3.82 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 7,481 mm³, 6.8% below the reference mean. With a Z-score of -0.68 (24.8th percentile), this represents normal volume ; whole brain volume measures 1,094,500 mm³, 3.5% below the reference mean. With a Z-score of -0.50 (30.9th percentile), this represents normal volume ; entorhinal cortex volume measures 3,060 mm³, 28.2% below the reference mean. With a Z-score of -1.95 (2.5th percentile), this represents moderate atrophy; fusiform gyrus volume measures 18,778 mm³, 5.7% below the reference mean. With a Z-score of -0.47 (31.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,068 mm³, 23.8% below the reference mean. With a Z-score of -1.96 (2.5th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 65.3 years. Gender is Male. Education: 16 years. MMSE: 17.0. Logical Memory: 1.0. Laboratory findings: Basophils: 0.09 (significant elevated); Alkaline Phosphatase: 121.00 (significant elevated); ALT (SGPT): 35.00 (significant elevated). APOEε4 alleles: 0.0.

  "gpt_diagnosis": "**Reasoning:** The data shows profound ventricular enlargement (Z-score 3.82) and moderate atrophy in the entorhinal cortex (Z-score -1.95) and middle temporal gyrus (Z-score -1.96), which are key regions affected in Alzheimer's disease. The MMSE score of 17 indicates significant cognitive impairment, consistent with dementia.  \n\n**Diagnosis:** Dementia (likely Alzheimer’s disease)  \n**Confidence:** High",
