  "img_finding": "Image findings: ventricular volume measures 25,551 mm³, 14.9% below the reference mean. With a Z-score of -0.35 (36.2th percentile), this represents normal volume ; hippocampal volume measures 8,811 mm³, 9.8% above the reference mean. With a Z-score of 0.98 (83.5th percentile), this represents normal volume ; whole brain volume measures 1,063,690 mm³, 6.2% below the reference mean. With a Z-score of -0.88 (18.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,930 mm³, 7.8% below the reference mean. With a Z-score of -0.54 (29.4th percentile), this represents normal volume ; fusiform gyrus volume measures 17,074 mm³, 14.2% below the reference mean. With a Z-score of -1.18 (11.8th percentile), this represents mild atrophy; middle temporal gyrus volume measures 19,463 mm³, 13.2% below the reference mean. With a Z-score of -1.08 (13.9th percentile), this represents mild atrophy. ",
  "text_data": "Age is 69.3 years. Gender is Male. Education: 16 years. MMSE: 29.0. MoCA: 27.0. Laboratory findings: Eosinophils: 0.51 (profound elevated); Eosinophils: 6.50 (significant elevated). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume data shows mild atrophy in the fusiform gyrus and middle temporal gyrus, but all other regions (ventricular, hippocampal, whole brain, entorhinal cortex) are within normal ranges. Cognitive scores (MMSE 29, MoCA 27) are intact, and APOE4 status (heterozygous) does not strongly indicate imminent decline.  \n\n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **Medium** (Mild atrophy in some regions could suggest early changes, but cognitive performance remains strong.)",
