  "img_finding": "Image findings: ventricular volume measures 81,958 mm³, 192.0% above the reference mean. With a Z-score of 4.40 (100.0th percentile), this represents profound enlargement; whole brain volume measures 846,724 mm³, 13.1% below the reference mean. With a Z-score of -1.65 (4.9th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (Z-score 4.40) and moderate whole brain atrophy (Z-score -1.65), which are strong indicators of neurodegenerative changes. Combined with cognitive test scores (MMSE 22, MoCA 15) below typical cutoffs for normal cognition, this suggests significant cognitive impairment.  \n\nDiagnosis: Dementia  \nConfidence: High",
