  "img_finding": "Image findings: ventricular volume measures 9,393 mm³, 66.5% below the reference mean. With a Z-score of -1.52 (6.4th percentile), this represents moderate atrophy; hippocampal volume measures 6,918 mm³, 2.8% below the reference mean. With a Z-score of -0.25 (40.0th percentile), this represents normal volume ; whole brain volume measures 936,796 mm³, 3.9% below the reference mean. With a Z-score of -0.49 (31.2th percentile), this represents normal volume ; entorhinal cortex volume measures 4,064 mm³, 10.6% above the reference mean. With a Z-score of 0.65 (74.3th percentile), this represents normal volume ; fusiform gyrus volume measures 18,104 mm³, 6.4% above the reference mean. With a Z-score of 0.58 (72.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,817 mm³, 1.8% below the reference mean. With a Z-score of -0.16 (43.7th percentile), this represents normal volume . ",
  "text_data": "Age is 72.6 years. Gender is Female. Education: 17 years. MMSE: 29.0. Logical Memory: 15.0. Laboratory findings: Eosinophils: 0.52 (profound elevated); Basophils: 0.12 (profound elevated); Eosinophils: 8.20 (profound elevated); Basophils: 1.80 (profound elevated). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume shows moderate atrophy (Z-score -1.52), but hippocampal, whole brain, and other regional volumes are within normal ranges. The MMSE score of 29 is intact, and there are no significant cognitive deficits reported.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (ventricular enlargement may suggest early changes, but no other structural or cognitive impairments support MCI or dementia at this stage)",
