【摘要】 目的　探讨CO中毒后苍白球的MRI表现。方法　分析了15例CO中毒患者出现双侧苍白球T1WI、T2WI的信号改变。结果　CO中毒苍白球信号改变主要为双侧对称,急性期主要表现为T1WI为等信号,T2WI为高或中心中等、外周高信号;出现迟发性脑病主要表现为T1WI为低信号,T2WI为高信号改变;恢复期主要表现为T1WI为很低信号,T2WI为高信号脑软化改变。结论　苍白球MRI信号改变对判断CO中毒的预后有参考价值。更多还原

【Abstract】 Objective To study MRI Signal Change of globus pallidus in CO poisoning. Methods MRI signal change of T1WI and T2WI of 15 patients with CO poisoning were analysed. Results The main MRI signal change of globus pallidus in CO Poisoning was symmetry in twin sides, the early lesions were medium signal intensities of T1WI, high signal or medium signal in center and high intensities in around of T2WI; The DNS was ariseed, main signal intensities were low in T1WI,high in T2WI; the main signal intensities of convalescence were very low in T1WI,high in T2WI, bain were softens the alteration. Conclusion MRI signal change of globus pallidus in CO Poisoning is very value in evaluating prognosis.更多还原
