  "img_finding": "Image findings: ventricular volume measures 37,587 mm³, 2.4% below the reference mean. With a Z-score of -0.06 (47.7th percentile), this represents normal volume ; hippocampal volume measures 5,520 mm³, 27.0% below the reference mean. With a Z-score of -2.63 (0.4th percentile), this represents significant atrophy; whole brain volume measures 946,609 mm³, 12.3% below the reference mean. With a Z-score of -1.60 (5.5th percentile), this represents moderate atrophy; entorhinal cortex volume measures 3,557 mm³, 13.3% below the reference mean. With a Z-score of -0.90 (18.4th percentile), this represents normal volume ; fusiform gyrus volume measures 15,013 mm³, 20.3% below the reference mean. With a Z-score of -1.73 (4.2th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 15,984 mm³, 25.1% below the reference mean. With a Z-score of -2.26 (1.2th percentile), this represents significant atrophy. ",
  "text_data": "Age is 79.1 years. Gender is Male. Education: 16 years. MMSE: 18.0. Logical Memory: 1.0. Laboratory findings: Neutrophils: 77.10 (significant elevated); Total Bilirubin: 1.40 (profound elevated); Serum Glucose: 62.00 (significant reduced); Direct Bilirubin: 0.40 (profound elevated).

  "gpt_diagnosis": "Reasoning: The patient shows significant hippocampal atrophy (Z-score -2.63, 0.4th percentile) and moderate-to-severe atrophy in other key regions (whole brain, fusiform gyrus, middle temporal gyrus), alongside a low MMSE score (18/30) and APOE4 homozygosity, strongly suggesting neurodegenerative pathology consistent with Alzheimer's disease.  \nDiagnosis: **Dementia** (likely Alzheimer’s disease)  \nConfidence: **High**",
