摘要
目的:探讨16排螺旋CT对颈动脉体瘤的诊断及术式选择的应用价值。材料与方法应用16排螺旋CT对12例彩色超声多普勒诊断颈动脉体瘤患者行CT颈部血管造影CTA(即CT增强检查),采用容积再现(VR)、最大密度投影(MIP)、多平面重建(MPR)技术处理图像。结果:12例肿瘤均位于颈总动脉分叉处,平扫为等密度或稍高密度,边界清楚,增强扫描呈明显强化,颈内外动脉分离,角度增大.结论:16排螺旋CT对于颈动脉体瘤的诊断和术式选择起着重要作用。
Object To study the value 16-slice Spiral CT angiography in the diagnosis of Carotid-body tumor and choice of modus operandi. Material and methods 12 patients with Carotid body tumor were examined with CTA ,all performed Volume Rendering （VR）. Maximum Intensity Projection （MIP）. Multiplanar （MPR）o Results Situating at the bifurcation of the common carotid artery, the tumors presented is-or high-density mass with defined margin and marked enhancement in CT. Conclusion 16-slice Spiral CT is of great value in the diagnosis of Carotid body tumor and choice of modus operandi.
