  "img_finding": "Image findings: ventricular volume measures 21,876 mm³, 12.5% below the reference mean. With a Z-score of -0.17 (43.4th percentile), this represents normal volume ; hippocampal volume measures 8,610 mm³.; whole brain volume measures 1,201,610 mm³, 0.8% above the reference mean. With a Z-score of 0.15 (55.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,371 mm³, 9.2% above the reference mean. With a Z-score of 0.81 (79.0th percentile), this represents normal volume ; fusiform gyrus volume measures 22,230 mm³, 6.7% above the reference mean. With a Z-score of 1.01 (84.4th percentile), this represents mild enlargement; middle temporal gyrus volume measures 21,665 mm³.. ",
  "text_data": "Age is 59.9 years. Gender is Male. Education: 16 years. MMSE: 30.0. MoCA: 24.0. Logical Memory: 8.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are all within normal ranges or mildly enlarged, with no significant atrophy. The MMSE score of 30 is normal, but the MoCA score of 24 suggests mild cognitive impairment (MCI). The presence of one APOE4 allele increases Alzheimer's risk but does not confirm pathology.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (due to normal imaging but borderline MoCA and APOE4 carrier status)",
