  "img_finding": "Image findings: ventricular volume measures 67,682 mm³, 75.7% above the reference mean. With a Z-score of 1.81 (96.5th percentile), this represents moderate enlargement; whole brain volume measures 897,197 mm³, 16.9% below the reference mean. With a Z-score of -2.19 (1.4th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant whole brain atrophy (Z-score -2.19, 1.4th percentile) and moderate ventricular enlargement (Z-score 1.81, 96.5th percentile), which are strong indicators of neurodegeneration. Combined with the patient's age, APOE4 homozygosity, and borderline MMSE score (25/30), this suggests cognitive impairment beyond normal aging.  \n\nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: High",
