3D-TOF MRA在颅内动脉瘤诊断中的应用

The Application of 3D-TOF MRA in the Diagnosis of Intracranial Aneurysms

目的:探讨磁共振血管成像3D-TOF序列在颅内动脉瘤诊断中的应用价值。方法:采用西门子3.0T超导磁共振对260例脑血管病患者进行颅脑MR平扫及MRA检查,其中有36例经DSA确诊有动脉瘤。结果:磁共振3D-TOF序列能清楚显示颅内动脉瘤的大小、瘤颈宽度等信息,尤其对Willis环周围的动脉瘤显示较好,对诊断有很大帮助。结论:磁共振3D-TOF序列作为一种无创、简便的检查方法对颅内动脉瘤的诊断有一定的临床应用价值。

Objective： To explore the application of 3D-TOF MRA in the diagnosis of intracranial aneurysms. Methods： Siemens 3.0 T magnetic resonance was used for carrying on the MRA to 260 cases cerebrovascular disease, and 36 cases were diagnosed aneurysm by DSA. Results： Magnetic resonance of 3D-TOF sequence can demonstrate the size of intracranial aneurysms and the width of tumor neck,especially for aneurysm around the Willis ring, very helpful for diagnosis. Conclusion： Magnetic resonance of 3D-TOF sequence is a noninvasive, safe technique, it＇s useful to the clinical application value in the diagnosis of intracranial aneurysms.
