  "img_finding": "Image findings: ventricular volume measures 69,042 mm³, 79.2% above the reference mean. With a Z-score of 1.90 (97.1th percentile), this represents moderate enlargement; whole brain volume measures 855,827 mm³, 20.7% below the reference mean. With a Z-score of -2.69 (0.4th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant whole brain atrophy (Z-score -2.69, 0.4th percentile) and moderate ventricular enlargement (Z-score 1.90, 97.1th percentile), consistent with advanced neurodegeneration. The very low MMSE (12) and MoCA (4) scores strongly indicate severe cognitive impairment.  \nDiagnosis: Dementia  \nConfidence: High",
