传统检测法和弛豫加强快速检测法(RARE)难以发现皮质梗死。MRI检测脑梗死虽比CT优越,但可能发现不了超急性梗死。而液相衰减反向回复法(flu-id-attenuated inversion recovery,FLAIR)及变更是MRI所显示的T_2加权影像和被抑制脑脊液信号的结果,它以180度反向脉冲传统自旋回波(SE)为先导。本文为评价加速FLAIR在大脑梗死诊断中的作用,回顾性地选择50例疑为脑血管意外而接受系列MRI研究的病
Traditional detection and relaxation enhanced rapid test (RARE) is difficult to detect cortical infarction. MRI detection of cerebral infarction superior to CT, but may not find hyperacute infarction. However, the FLAIR and its changes were the results of T_2 -weighted images and suppressed cerebrospinal fluid signals displayed by MRI. The results showed that FLAIR ) As the guide. In this review, we evaluated the role of accelerated FLAIR in the diagnosis of cerebral infarction. We retrospectively selected 50 patients suspected of having a cerebrovascular accident who underwent series of MRI studies
