  "img_finding": "Image findings: ventricular volume measures 36,022 mm³, 28.3% above the reference mean. With a Z-score of 0.65 (74.2th percentile), this represents normal volume ; hippocampal volume measures 8,128 mm³, 14.2% above the reference mean. With a Z-score of 1.31 (90.4th percentile), this represents mild enlargement; whole brain volume measures 995,915 mm³, 2.2% above the reference mean. With a Z-score of 0.27 (60.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,754 mm³, 2.2% above the reference mean. With a Z-score of 0.14 (55.4th percentile), this represents normal volume ; fusiform gyrus volume measures 19,123 mm³, 12.4% above the reference mean. With a Z-score of 1.13 (87.0th percentile), this represents mild enlargement; middle temporal gyrus volume measures 21,141 mm³, 10.3% above the reference mean. With a Z-score of 0.89 (81.4th percentile), this represents normal volume . ",
  "text_data": "Age is 78.1 years. Gender is Female. Education: 14 years. MMSE: 27.0. MoCA: 24.0. Logical Memory: 16.0. Laboratory findings: Eosinophils: 0.40 (significant elevated); Basophils: 0.12 (profound elevated); Eosinophils: 7.00 (profound elevated); Basophils: 2.00 (profound elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "**Reasoning:** The brain volume measurements show normal or mildly enlarged structures, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. Cognitive scores (MMSE 27, MoCA 24) are within normal or mild cognitive impairment (MCI) ranges, but the absence of APOE4 and preserved brain volumes suggest no clear neurodegenerative pathology.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to borderline MoCA score but otherwise normal biomarkers)",
