  "img_finding": "Image findings: ventricular volume measures 56,674 mm³, 153.7% above the reference mean. With a Z-score of 3.85 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 6,680 mm³, 13.1% below the reference mean. With a Z-score of -1.47 (7.1th percentile), this represents mild atrophy; whole brain volume measures 1,080,300 mm³, 5.0% above the reference mean. With a Z-score of 0.62 (73.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,995 mm³, 2.6% above the reference mean. With a Z-score of 0.20 (58.0th percentile), this represents normal volume ; fusiform gyrus volume measures 20,432 mm³, 12.2% above the reference mean. With a Z-score of 1.37 (91.5th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,564 mm³, 4.7% below the reference mean. With a Z-score of -0.41 (33.9th percentile), this represents normal volume . ",
  "text_data": "Age is 68.3 years. Gender is Female. Education: 14 years. MMSE: 29.0. MoCA: 24.0. Laboratory findings: Eosinophils: 0.37 (significant elevated); Basophils: 0.10 (significant elevated); Cholesterol (High Performance): 358.00 (profound elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The data shows profound ventricular enlargement (Z-score 3.85) and mild hippocampal atrophy (Z-score -1.47), both suggestive of neurodegenerative changes. However, cognitive scores (MMSE 29, MoCA 24) are borderline for MCI, with no APOE4 risk allele.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to conflicting imaging and cognitive findings—ventricular enlargement strongly suggests pathology, but MoCA is only slightly below normal)",
