  "img_finding": "Image findings: ventricular volume measures 66,132 mm³, 71.7% above the reference mean. With a Z-score of 1.72 (95.7th percentile), this represents moderate enlargement; hippocampal volume measures 4,735 mm³, 37.4% below the reference mean. With a Z-score of -3.64 (0.0th percentile), this represents profound atrophy; whole brain volume measures 917,654 mm³, 15.0% below the reference mean. With a Z-score of -1.95 (2.6th percentile), this represents moderate atrophy; entorhinal cortex volume measures 2,453 mm³, 40.2% below the reference mean. With a Z-score of -2.72 (0.3th percentile), this represents significant atrophy; fusiform gyrus volume measures 13,759 mm³, 27.0% below the reference mean. With a Z-score of -2.30 (1.1th percentile), this represents significant atrophy; middle temporal gyrus volume measures 15,849 mm³, 25.7% below the reference mean. With a Z-score of -2.31 (1.0th percentile), this represents significant atrophy. ",
  "text_data": "Age is 76.4 years. Gender is Male. Education: 17 years. MMSE: 17.0. MoCA: 7.0. Laboratory findings: Monocytes: 0.86 (profound elevated); Monocytes: 10.10 (significant elevated); RBC: 5.80 (significant elevated); Triglycerides (GPO): 240.00 (significant elevated).

  "gpt_diagnosis": "**Reasoning:** The data shows profound hippocampal atrophy (Z-score -3.64), significant entorhinal cortex and temporal lobe atrophy, and moderate whole-brain atrophy, all consistent with Alzheimer's disease. The cognitive scores (MMSE 17, MoCA 7) indicate severe impairment, aligning with structural degeneration.  \n\n**Diagnosis:** Dementia (likely Alzheimer’s disease)  \n**Confidence:** High",
