颈动脉体瘤影像学特征比较研究

目的比较彩色多普勒超声(CDFI)、磁共振影像(MRI)、磁共振血管成像(MRA)、数字减影血管造影(DSA)在颈动脉体瘤诊断中的影像学特征。方法对8例经手术病理证实颈动脉体瘤患者进行了CDFI、MRI、MRA、DSA影像学特征比较。结果颈动脉体瘤CDFI、MRI、MRA、DSA影像学特征有:颈总动脉分叉处单发性肿块,并与颈动脉紧密相连,瘤体内血流极为丰富,瘤体使颈外动脉向前内移位、颈内动脉向后外移位,颈内外动脉分叉角度增大明显,MRA及DSA呈"Goldcup"征改变。结论CDFI、DSA、MRA均有明确的颈动脉体瘤影像学特征,在颈动脉体瘤诊断上具有重要的临床实用价值。

Comparative study on imaging features of carotid body tumor

Objective To compare imaging features of carotid body tumor (CBT) in diagnosis. Methods The clinical data of 8 patients with CBT treated in our hospital from 1990 to 2005 were retrospectively compared with color Doppler flow imaging(CDFI),magnetic resonance imaging (MRI),magnetic resonance angiography (MRA),and digital subtraction angiography (DSA). Results The imaging features of 8 patients with CBT were located at the bifurcation of carotid artery,carotid artery grasped tumor,blood supply in the tumor was abundant,internal and external carotid shifted,and the bifurcation of carotid artery increased and showed Goldcup change in DSA and MRA. Conclusions Manifestations of CBT have its own imaging characteristics in CDFI,DSA and MRA. It has an important value in the diagnosis of CBT with CDFI,DSA and MRA.
