  "img_finding": "Image findings: ventricular volume measures 20,035 mm³, 48.0% below the reference mean. With a Z-score of -1.15 (12.5th percentile), this represents mild atrophy; hippocampal volume measures 8,030 mm³, 6.2% above the reference mean. With a Z-score of 0.61 (72.8th percentile), this represents normal volume ; whole brain volume measures 1,272,170 mm³, 17.9% above the reference mean. With a Z-score of 2.32 (99.0th percentile), this represents significant enlargement; entorhinal cortex volume measures 5,321 mm³, 29.8% above the reference mean. With a Z-score of 2.02 (97.8th percentile), this represents significant enlargement; fusiform gyrus volume measures 23,000 mm³, 22.1% above the reference mean. With a Z-score of 1.88 (97.0th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 23,026 mm³, 7.9% above the reference mean. With a Z-score of 0.71 (76.1th percentile), this represents normal volume . ",
  "text_data": "Age is 76.3 years. Gender is Male. Education: 15 years. MMSE: 30.0. MoCA: 23.0. Laboratory findings: MCHC: 36.00 (significant elevated); Basophils: 0.11 (significant elevated); Basophils: 2.10 (profound elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain imaging shows mild ventricular atrophy but otherwise normal-to-enlarged volumes in key regions (hippocampus, entorhinal cortex, fusiform gyrus, middle temporal gyrus). The MMSE is normal (30/30), but the MoCA (23/30) suggests mild cognitive impairment. The absence of APOE4 reduces genetic risk.  \n**Diagnosis:** **MCI** (due to MoCA score despite largely preserved brain volumes)  \n**Confidence:** **Medium** (conflicting imaging and cognitive findings; MoCA is borderline but not strongly indicative of dementia)",
