  "img_finding": "Image findings: ventricular volume measures 49,454 mm³, 28.4% above the reference mean. With a Z-score of 0.68 (75.2th percentile), this represents normal volume ; hippocampal volume measures 8,796 mm³, 16.4% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement; whole brain volume measures 1,115,160 mm³, 3.3% above the reference mean. With a Z-score of 0.43 (66.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,688 mm³, 10.1% below the reference mean. With a Z-score of -0.68 (24.8th percentile), this represents normal volume ; fusiform gyrus volume measures 19,770 mm³, 4.9% above the reference mean. With a Z-score of 0.42 (66.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,831 mm³, 11.7% above the reference mean. With a Z-score of 1.05 (85.3th percentile), this represents mild enlargement. ",
  "text_data": "Age is 79.2 years. Gender is Male. Education: 14 years. MMSE: 29.0. MoCA: 25.0. Logical Memory: 5.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is moderately enlarged (94.5th percentile), while the entorhinal cortex is slightly below average (24.8th percentile). Cognitive scores (MMSE 29, MoCA 25) are within normal limits for age, and there are no significant atrophy markers in most regions.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to the slightly reduced entorhinal cortex volume, but cognitive scores and other volumes are normal)",
