  "img_finding": "Image findings: ventricular volume measures 34,093 mm³, 11.5% below the reference mean. With a Z-score of -0.28 (39.2th percentile), this represents normal volume ; hippocampal volume measures 6,826 mm³, 9.7% below the reference mean. With a Z-score of -0.95 (17.2th percentile), this represents normal volume ; whole brain volume measures 1,010,090 mm³, 6.4% below the reference mean. With a Z-score of -0.83 (20.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,615 mm³, 11.8% below the reference mean. With a Z-score of -0.80 (21.1th percentile), this represents normal volume ; fusiform gyrus volume measures 17,882 mm³, 5.1% below the reference mean. With a Z-score of -0.43 (33.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,333 mm³, 14.1% below the reference mean. With a Z-score of -1.27 (10.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 78.3 years. Gender is Male. Education: 16 years. MMSE: 27.0. Logical Memory: 18.0. Laboratory findings: Total Bilirubin: 0.80 (significant elevated); Creatinine (Rate Blanked): 1.70 (profound elevated); Serum Uric Acid: 8.40 (significant elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "**Reasoning:** All brain volumes are within normal ranges except for mild atrophy in the middle temporal gyrus. The MMSE score of 27 is within the normal range (≥26), and the absence of APOE4 alleles reduces genetic risk. No significant cognitive impairment is indicated.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (mild atrophy in the middle temporal gyrus warrants monitoring but does not yet suggest MCI or dementia)",
