  "img_finding": "Image findings: ventricular volume measures 37,310 mm³, 20.6% below the reference mean. With a Z-score of -0.60 (27.4th percentile), this represents normal volume ; hippocampal volume measures 6,796 mm³, 2.5% below the reference mean. With a Z-score of -0.21 (41.5th percentile), this represents normal volume ; whole brain volume measures 1,007,950 mm³, 2.1% below the reference mean. With a Z-score of -0.27 (39.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,349 mm³, 15.6% below the reference mean. With a Z-score of -1.02 (15.3th percentile), this represents mild atrophy; fusiform gyrus volume measures 18,267 mm³, 1.1% above the reference mean. With a Z-score of 0.10 (53.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,299 mm³, 4.3% below the reference mean. With a Z-score of -0.39 (34.9th percentile), this represents normal volume . ",
  "text_data": "Age is 84.7 years. Gender is Male. Education: 12 years. MMSE: 28.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volume measurements show mostly normal values, with only mild atrophy in the entorhinal cortex (Z-score -1.02, 15.3th percentile). The MMSE score of 28 is within the normal range, and there is no APOE4 genetic risk factor present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild entorhinal cortex atrophy, but no other significant indicators of cognitive decline)",
