Diagnostic value and imaging identities for carotid body tumor by 64-MSCTA

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.
