脑血管性病变的多排螺旋CT诊断

目的：探讨多排螺旋CT血管成像在评价颅内血管性病变中的应用价值。方法对诊断为脑血管病变的98例患者的CT影像资料进行回顾性分析，总结其诊断方法、影像学表现及临床应用价值。同时与数字减影血管造影（DSA）结果对照。结果多排螺旋CT血管成像检出颅内动脉瘤47例，脑血管畸形14例，闭塞性脑血管病变25例，烟雾病5例，颈内动脉海绵窦瘘3例，脑血管发育异常9例，脑肿瘤（显示肿瘤供血血管）3例。结论多排螺旋CT脑血管成像是诊断脑血管病变的首选非创伤性检查方法，同时可以为颅内血管性病变治疗方案的选择提供客观的参考依据。

Diagnosis of multi-slice spiral CT in cerebral vascular lesions

Objective To explore diagnostic value of the multi-Slice CT angiography in the intracranial vascular diseases. Methods 98 patients of cerebrovascular desease of the CT imaging data of were retrospectively analyzed, summarized diagnosis method,imaging manifestations and clinical application value. Results Multi-Slice CT angiography imaging showed 47 cases of intracranial aneurysms,vascular malformations 14 cases,25 cases of occlusive cerebrovascular lesions 5 cases of moyamoya disease,3 cases carotid cavernous fistula,9 cases of cerebral dysplasia.3 cases of Brain tumor （display the tumor blood vessels）.Comparison with the results of angiography （DSA）. Conclusion Multi-slice CT cerebral imaging is the preferred method in diagnosis of cerebrovascular desease,and the choice of treatment for intracranial vascular diseases to provide objective reference basis.
