Rapid sequence CT imaging provides information about the vascular anatomy (CT angiography), locates major vessels encased by tumor, and eliminates the possibility of avascular lesions in the differential diagnosis of a head and neck tumor. Furthermore the use of density-time curves allows arterial and venous time. The patterns of density-time curves are characteristic for various lesions. For glomus complex tumors, regardless of the size and location, dynamic CT easily differentiates them from most of the simulating lesions. Angiography therefore is occasionally necessary for verification. Dynamic CT has a risk of complications the same as that of any intravenous injection of contrast material. Cerebral angiography via the femoral approach has been reported to have a risk of major complications of 0.28% and of minor complications of 6.25%.
快速序列CT成像可提供有关血管解剖结构的信息（CT血管造影），定位被肿瘤包裹的主要血管，并在头颈部肿瘤的鉴别诊断中排除无血管病变的可能性。此外，使用密度-时间曲线可得出动脉期和静脉期时间。密度-时间曲线的模式对各种病变具有特征性。对于副神经节瘤，无论其大小和位置如何，动态CT都能轻松将其与大多数类似病变区分开来。因此，偶尔需要进行血管造影以进行验证。动态CT与任何静脉注射造影剂一样存在并发症风险。据报道，经股动脉途径进行脑血管造影的主要并发症风险为0.28%，次要并发症风险为6.25%。
