  "img_finding": "Image findings: ventricular volume measures 16,612 mm³, 40.8% below the reference mean. With a Z-score of -0.93 (17.5th percentile), this represents normal volume ; hippocampal volume measures 6,933 mm³, 2.6% below the reference mean. With a Z-score of -0.23 (40.7th percentile), this represents normal volume ; whole brain volume measures 1,044,800 mm³, 7.2% above the reference mean. With a Z-score of 0.91 (81.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,812 mm³, 3.8% above the reference mean. With a Z-score of 0.23 (59.2th percentile), this represents normal volume ; fusiform gyrus volume measures 17,879 mm³, 5.1% above the reference mean. With a Z-score of 0.46 (67.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,076 mm³, 5.7% below the reference mean.

  "text_data": "Age is 77.6 years. Gender is Female. Education: 12 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Major Surgical Procedures. MMSE: 28.0. MoCA: 21.0. Logical Memory: 5.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The brain volumes (hippocampus, entorhinal cortex, fusiform gyrus, etc.) are within normal ranges, with no significant atrophy. However, the MoCA score of 21 suggests mild cognitive impairment, while the MMSE of 28 is borderline normal. The presence of one APOE4 allele increases Alzheimer's risk but is not definitive.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (MoCA indicates impairment, but structural imaging is normal, and MMSE is near-normal)",
