  "img_finding": "Image findings: ventricular volume measures 28,503 mm³, 14.0% above the reference mean. With a Z-score of 0.19 (57.4th percentile), this represents normal volume ; hippocampal volume measures 9,054 mm³.; whole brain volume measures 1,321,880 mm³, 10.9% above the reference mean. With a Z-score of 2.02 (97.8th percentile), this represents significant enlargement; entorhinal cortex volume measures 4,258 mm³, 6.4% above the reference mean. With a Z-score of 0.56 (71.2th percentile), this represents normal volume ; fusiform gyrus volume measures 19,411 mm³, 6.9% below the reference mean. With a Z-score of -1.04 (14.8th percentile), this represents mild atrophy; middle temporal gyrus volume measures 25,424 mm³.. ",
  "text_data": "Age is 58.1 years. Gender is Male. Education: 16 years. MMSE: 28.0. Logical Memory: 4.0. Laboratory findings: Total Bilirubin: 1.10 (profound elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume (9,054 mm³) is within normal range, and other key regions (ventricular, entorhinal cortex) show no significant atrophy. The fusiform gyrus has mild atrophy, but the MMSE score (28/30) is normal, and the absence of APOE4 reduces Alzheimer's risk.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (mild fusiform atrophy is atypical but not strongly indicative of pathology given other normal findings)",
