  "img_finding": "Image findings: ventricular volume measures 28,112 mm³, 6.4% below the reference mean. With a Z-score of -0.15 (44.0th percentile), this represents normal volume ; whole brain volume measures 1,050,430 mm³, 7.4% below the reference mean. With a Z-score of -1.05 (14.7th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,970 mm³, 6.9% below the reference mean. With a Z-score of -0.48 (31.7th percentile), this represents normal volume ; fusiform gyrus volume measures 17,077 mm³, 14.2% below the reference mean. With a Z-score of -1.18 (11.8th percentile), this represents mild atrophy; middle temporal gyrus volume measures 19,156 mm³, 14.5% below the reference mean. With a Z-score of -1.20 (11.6th percentile), this represents mild atrophy. ",
  "text_data": "Age is 67.5 years. Gender is Male. Education: 13 years. MMSE: 28.0. MoCA: 22.0. Logical Memory: 7.0. Laboratory findings: Triglycerides (GPO): 382.00 (profound elevated). APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The imaging shows mild atrophy in the whole brain, fusiform gyrus, and middle temporal gyrus, while ventricular and entorhinal cortex volumes are normal. The MoCA score of 22 suggests mild cognitive impairment, but the MMSE of 28 is within normal limits. The presence of one APOE4 allele increases Alzheimer's risk but is not definitive.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
