  "img_finding": "Image findings: ventricular volume measures 54,572 mm³, 118.2% above the reference mean. With a Z-score of 1.57 (94.2th percentile), this represents moderate enlargement; hippocampal volume measures 6,444 mm³.; whole brain volume measures 900,839 mm³, 24.4% below the reference mean. With a Z-score of -4.52 (0.0th percentile), this represents profound atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound whole brain atrophy (Z-score -4.52) and moderate ventricular enlargement, along with significant cognitive impairment (MMSE 13). These findings, combined with the presence of one APOE4 allele, strongly suggest neurodegenerative disease.  \nDiagnosis: Dementia  \nConfidence: High",
