  "img_finding": "Image findings: ventricular volume measures 19,844 mm³, 29.3% below the reference mean. With a Z-score of -0.67 (25.1th percentile), this represents normal volume ; hippocampal volume measures 6,193 mm³, 13.0% below the reference mean. With a Z-score of -1.19 (11.7th percentile), this represents mild atrophy; whole brain volume measures 847,274 mm³, 13.1% below the reference mean. With a Z-score of -1.65 (5.0th percentile), this represents moderate atrophy; entorhinal cortex volume measures 3,014 mm³, 17.9% below the reference mean. With a Z-score of -1.10 (13.5th percentile), this represents mild atrophy; fusiform gyrus volume measures 15,023 mm³, 11.7% below the reference mean. With a Z-score of -1.06 (14.4th percentile), this represents mild atrophy; middle temporal gyrus volume measures 16,376 mm³, 14.6% below the reference mean. With a Z-score of -1.26 (10.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 70.3 years. Gender is Female. Education: 12 years. MMSE: 28.0. MoCA: 26.0. Logical Memory: 11.0. APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus volumes show mild to moderate atrophy, which is concerning for neurodegenerative changes. However, cognitive scores (MMSE 28, MoCA 26) remain within normal limits, suggesting no significant functional impairment.  \nDiagnosis: **Mild Cognitive Impairment (MCI)**  \nConfidence: **Medium** (Structural atrophy is present, but cognitive performance is preserved, making early MCI more likely than dementia or normal aging.)",
