64层螺旋CT脑血管造影对脑血管病变的诊断价值

Diagnoses Evaluation of 64-slice Spiral CT Angiography in Cerebral Vascular Lesions

目的:探讨64层螺旋CT脑血管造影对脑血管病的诊断价值。方法:对临床怀疑为脑血管病变的48例患者进行64层螺旋CT血管造影,使用TOSHIBA Aquilion64层螺旋CT机。获得原始图像传送到工作站进行VR、MPR、CPR、MIP图像后处理重建,并对照手术或DSA结果评估其诊断价值。结果:48例中发现30例动脉瘤、4例动静脉畸形、8例脑动脉狭窄或闭塞、6例无异常发现。结论:64层螺旋CT脑血管造影对多种脑血管病的诊断具有肯定的临床应用价值。

Objective To explore the diagnosis evaluation of 64-slice spiral CT angiography（CTA） in cerebral vascular disease. Methods 64-slice spiral CT angiography of 48 patients with suspected clinically cerebral vascular diseases were analyzed retrospectively. The source images were got by TOSHIBA Aquilion VCT Scanner, and all axial images were transferred to an external workstation. The reconstructed images were processed into volume rendering（VR）, multiplanner reconstruction（MPR） and maximum intensity projection（MIP）, the values were valuably compared with the results of surgery or DSA. Results 30 cases were aneurysms, 4 cases were AVM, 8 cases were cerebral artery stenosis or occlusion, 6 cases were normal. Conclusion The 64-slice spiral CTA is a valuable diagnostic method for various cerebral vascular diseases.
