  "img_finding": "Image findings: ventricular volume measures 129,863 mm³, 165.7% above the reference mean. With a Z-score of 15.01 (100.0th percentile), this represents profound enlargement; whole brain volume measures 1,152,250 mm³, 15.0% above the reference mean. With a Z-score of 2.56 (99.5th percentile), this represents significant enlargement. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (165.7% above reference mean, Z-score 15.01), which is strongly indicative of brain atrophy, a hallmark of neurodegenerative disease. However, the whole brain volume is also enlarged (15.0% above reference mean, Z-score 2.56), which is unusual for typical Alzheimer's progression. The MMSE score of 25 is borderline but does not strongly suggest dementia.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (due to conflicting volumetric findings and borderline MMSE)",
