  "img_finding": "Image findings: ventricular volume measures 19,710 mm³, 11.8% below the reference mean. With a Z-score of -0.29 (38.4th percentile), this represents normal volume ; whole brain volume measures 1,027,660 mm³, 0.1% below the reference mean. With a Z-score of -0.02 (49.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,478 mm³, 10.7% below the reference mean. With a Z-score of -0.83 (20.4th percentile), this represents normal volume ; fusiform gyrus volume measures 18,126 mm³, 0.5% below the reference mean. With a Z-score of -0.05 (47.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,879 mm³, 12.9% below the reference mean. With a Z-score of -1.14 (12.6th percentile), this represents mild atrophy. ",
  "text_data": "Age is 64.0 years. Gender is Female. Education: 15 years. MMSE: 30.0. MoCA: 26.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within normal ranges, with only mild atrophy noted in the middle temporal gyrus. Cognitive scores (MMSE 30, MoCA 26) are within normal limits, and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to mild atrophy in the middle temporal gyrus, but no significant cognitive impairment)",
