  "img_finding": "Image findings: ventricular volume measures 15,743 mm³, 15.5% below the reference mean. With a Z-score of -0.44 (32.9th percentile), this represents normal volume ; hippocampal volume measures 8,730 mm³, 11.8% above the reference mean. With a Z-score of 1.64 (95.0th percentile), this represents moderate enlargement; whole brain volume measures 1,007,590 mm³, 3.2% below the reference mean. With a Z-score of -0.38 (35.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,774 mm³, 2.1% above the reference mean. With a Z-score of 0.17 (56.6th percentile), this represents normal volume ; fusiform gyrus volume measures 18,167 mm³, 1.4% below the reference mean. With a Z-score of -0.13 (44.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,108 mm³, 2.8% above the reference mean. With a Z-score of 0.23 (59.1th percentile), this represents normal volume . ",
  "text_data": "Age is 57.5 years. Gender is Female. Education: 20 years. MMSE: 30.0. MoCA: 27.0. Laboratory findings: Eosinophils: 0.36 (significant elevated); Basophils: 0.15 (profound elevated); Eosinophils: 5.70 (significant elevated); Basophils: 2.30 (profound elevated). APOEε4 alleles: 2.0.

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within normal ranges, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. Cognitive scores (MMSE 30, MoCA 27) are normal, though the MoCA is slightly below the typical cutoff of 26 for MCI. The presence of two APOE4 alleles increases Alzheimer's risk but does not confirm pathology without clinical or biomarker evidence.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to APOE4 risk but normal imaging and cognitive scores)",
