  "img_finding": "Image findings: ventricular volume measures 56,378 mm³, 19.9% above the reference mean. With a Z-score of 0.58 (71.8th percentile), this represents normal volume ; hippocampal volume measures 6,125 mm³, 12.1% below the reference mean. With a Z-score of -1.05 (14.8th percentile), this represents mild atrophy; whole brain volume measures 1,088,810 mm³, 5.8% above the reference mean. With a Z-score of 0.76 (77.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,647 mm³, 8.1% below the reference mean. With a Z-score of -0.53 (29.8th percentile), this represents normal volume ; fusiform gyrus volume measures 15,445 mm³, 14.5% below the reference mean. With a Z-score of -1.26 (10.5th percentile), this represents mild atrophy; middle temporal gyrus volume measures 20,103 mm³, 0.3% below the reference mean. With a Z-score of -0.03 (48.8th percentile), this represents normal volume . ",
  "text_data": "Age is 81.2 years. Gender is Male. Education: 18 years. MMSE: 28.0. MoCA: 24.0. Laboratory findings: WBC: 9.79 (significant elevated); Neutrophils: 7.31 (profound elevated); Total Protein: 8.30 (profound elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The hippocampal and fusiform gyrus volumes show mild atrophy (Z-scores -1.05 and -1.26, respectively), which are early indicators of neurodegeneration. However, cognitive scores (MMSE 28, MoCA 24) are borderline normal for age, suggesting no significant functional impairment yet.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Structural changes are present, but cognitive performance is not yet clearly impaired enough for a dementia diagnosis.)",
