Methods 30 patients with SAH diagnosed by DSA, CT and operation, were given normal saline to exchange cerebrospinal fluid ( CSF) and injection of urokinase into vertebral canal. 方法对经DSA、CT、手术证实的30例SAH患者,用等量生理盐水置换脑脊液(CSF)和椎管内尿激酶(UK)注射治疗,并与对照组进行比较。
Conclusion: Abnormal high signal intensity of cerebrospinal fluid on T2-WI of SEO pulse sequence means obstruction of cerebrospinal fluid circulation and may suggest presence of intraspinal space occupied lesion or spinal canal stenosis. 结论:SEO序列T2WI上脑脊液信号的反常增高意味着脑脊液循环的梗阻,提示有椎管内占位病变或椎管狭窄的存在。
