  "img_finding": "Image findings: ventricular volume measures 48,036 mm³, 71.1% above the reference mean. With a Z-score of 1.63 (94.8th percentile), this represents moderate enlargement; hippocampal volume measures 5,870 mm³, 17.5% below the reference mean. With a Z-score of -1.60 (5.4th percentile), this represents moderate atrophy; whole brain volume measures 1,023,780 mm³, 5.0% above the reference mean. With a Z-score of 0.63 (73.7th percentile), this represents normal volume ; entorhinal cortex volume measures 2,799 mm³, 23.8% below the reference mean. With a Z-score of -1.46 (7.2th percentile), this represents mild atrophy; fusiform gyrus volume measures 17,636 mm³, 3.7% above the reference mean. With a Z-score of 0.33 (63.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,235 mm³, 5.6% above the reference mean. With a Z-score of 0.48 (68.5th percentile), this represents normal volume . ",
  "text_data": "Age is 72.3 years. Gender is Female. Education: 16 years. MMSE: 26.0. MoCA: 21.0. Logical Memory: 0.0. APOEε4 alleles: 2.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The data shows moderate hippocampal and entorhinal cortex atrophy, which are key regions affected in Alzheimer's disease. The MMSE (26) and MoCA (21) scores suggest mild cognitive impairment, and the presence of two APOE4 alleles increases Alzheimer's risk.  \nDiagnosis: MCI (likely due to Alzheimer's pathology)  \nConfidence: Medium (clinical and imaging findings align, but biomarker confirmation would strengthen certainty)",
