  "img_finding": "Image findings: ventricular volume measures 50,622 mm³, 126.6% above the reference mean. With a Z-score of 3.17 (99.9th percentile), this represents profound enlargement; hippocampal volume measures 6,473 mm³, 15.8% below the reference mean. With a Z-score of -1.77 (3.8th percentile), this represents moderate atrophy; whole brain volume measures 1,099,370 mm³, 6.8% above the reference mean. With a Z-score of 0.85 (80.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,969 mm³, 2.0% above the reference mean. With a Z-score of 0.15 (56.0th percentile), this represents normal volume ; fusiform gyrus volume measures 20,076 mm³, 10.2% above the reference mean. With a Z-score of 1.15 (87.6th percentile), this represents mild enlargement; middle temporal gyrus volume measures 22,244 mm³, 8.4% above the reference mean. With a Z-score of 0.75 (77.2th percentile), this represents normal volume . ",
  "text_data": "Age is 69.8 years. Gender is Female. Education: 18 years. MMSE: 29.0. MoCA: 25.0. Laboratory findings: Lymphocytes: 2.84 (significant elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The data shows profound ventricular enlargement (Z-score 3.17) and moderate hippocampal atrophy (Z-score -1.77), both of which are strong indicators of neurodegeneration. However, cognitive scores (MMSE 29, MoCA 25) are near-normal, suggesting preserved function despite structural changes.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Structural changes are concerning, but cognitive performance is not yet impaired enough for a dementia diagnosis. APOE4-negative status and preserved entorhinal/fusiform volumes provide some mitigating factors.)",
