摘要
目的探讨多层螺旋CT(MSCT)及重建技术在颈动脉体瘤诊断中的临床应用价值。方法回顾性分析经病理证实的11例颈动脉体瘤的颈部血管CT成像(MSCTA)、容积重建(VR)和多平面重建(MPR)的表现以及其中5例的数字减影血管造影(digital subtraction angiography,DSA)征象。结果11例病变均为单发并位于颈总动脉分叉处,CT平扫呈等密度软组织肿块,形状多较规则;增强扫描肿块明显强化,表面有丰富血管网,颈内、外动脉分叉角增大,其中3例瘤体较大并包绕颈动脉生长。MSCTA清晰显示肿块与颈总、颈内及颈外动脉的关系,并与5例DSA表现基本相似。结论MSCTA对于颈动脉体瘤有重要诊断价值,且对于指导临床选择手术方式有重要意义。
Objective To study the clinical value of multi-slice spiral CT （MSCT） row CT angiography （CTA） and its reconstruction techniques in the diagnosis of carotid body tumor. Methods The MSCT imaging data, including volume rendering（VR） and muhiplanar （MPR） of 11 cases of carotid body tumor proven pathologically and digital signal angiography（DSA） findings of 5 cases were retrospectively analyzed. Results Each of the 11 patients had one lesion and all lesions showing the similar density to muscle on non-contrast CT were located at the bifurcation of the common carotid artery. All masses were enhanced obviously after contrast media administration, with the enlarged angle between external and internal carotid arteries and carotid arteries encircled partially or entirely by the tumor in 3 cases. MSCT angiography （MSCTA） clearly showed the relationship between mass and carotid artery. DSA findings of 5 cases were similar to that of CTA. Conclusion MSCTA has significant value in diagnosing carotid body tumor and in selecting appropriate therapy in clinic.
