低场强MRI对急性CO中毒脑损伤的诊断价值

Diagnostic value of low-field MRI for acute poisoning brain injury

摘要:
目的探讨低场强MRI在急性CO中毒脑损伤诊断中的价值。
方法回顾性分析29例经临床确诊的急性CO中毒脑损伤患者的颅脑MRI和临床资料。
结果 CO中毒脑损伤的MRI表现主要为双侧大脑半球白质及苍白球出现长T1、长T2信号灶，两侧对称。MRI表现可分3型，即脑白质型、苍白球型及脑混合型。
结论 MRI检查可确定急性CO中毒脑损伤的程度及范围，对急性CO中毒脑损伤的治疗和判断预后有重要的临床指导价值。

Abstract:
Objective To investigate the value of low-field MIR in diagnosis of acute CO poisoning brain injury.
Methods The brain MIR and clinical data of 110 patients with acute CO poisoning brain injury confirmed by clinical examination were retrospectively analyzed.
Results Long T1 and T2 signal intensity was showed on MRI in cerebral hemispheres and globus pallidus symmetrically. There were three basic types of MIR manifestations, white matter of brain type, globus pallidus type and brain mixed type.
Conclusions MRI could be used for confirming the degree and range of acute CO poisoning brain injury. It has important clinical value in the diagnosis, staging and prognosis of patients with acute CO poisoning brain injury.
