摘要
目的：探讨64－MSCTA对颈动脉体瘤的诊断价值及其影像特征。方法：回顾性分析14例经临床和（或）病理证实的颈动脉体瘤多层螺旋CT增强扫描和CTA影像资料，评价64-MSCTA对颈动脉体瘤的诊断价值。结果：所有病例均显示为颈动脉分叉处的边界清晰、形态不规则的实性软组织肿物，14例均未见钙化；增强扫描动脉期肿块呈显著不均匀强化，瘤体内见丰富供血血管；静脉期肿瘤持续强化，强化程度低于动脉期，瘤体内密度趋向均匀；三维重建示肿瘤附着于颈动脉分叉部，多数病例见分叉角增大。结论：64-MSCTA多种重建技术可明确显示病灶大小、范围、境界、强化特征以及与邻近结构的关系，可提供更多鉴别诊断信息，可作为颈动脉体瘤的首选诊断方法。
Abstract
Objective: To study the value, technique and advantages of 64-MSCT angiography in the diagnosis of carotid body tumor. Methods: The CTA results of 14 cases with carotid body tumor confirmed by clinic and pathology were analysed retrospectively. The value of 64-MSCT angiography in the diagnosis of carotid body tumor were discussed. Results: ①Solitary lesion located at the bifurcation of carotid artery with irregular shape, clear edge, and no calcification was displayed in all cases; In arterial phase, the tumor was inhomogeneously evidently intensified with numerous tumor vessels; In venous phase, the enhanced degree of the tumor was lower than that in the arterial phase, tended to be homogeneous. ②The tumor usually was located at the bifurcation of external carotid artery and internal carotid artery. Most of the bifurcation angle was increased obviously. Conclusion: The 64-MSCT angiography has the advantage of convenience in performing, accuracy and specificity in features, is the method of choice in detecting carotid body tumor. Different kinds of reconstruction techniques showed the location, size, shape, and extent of the lesions and displayed the lesion in any directions, clearly displayed the relation between the tumor and carotid artery and show more reliable diagnostic information.
