Intravenous and intra-arterial digital subtraction angiography is able to demonstrate hypervascular tumours in the ear, nose and throat territory. Direct puncture of a venous bypass used for intra-arterial chemotherapy, within the external carotid artery territory, is devoid of risk and can be used for assessing the accessibility of the tumour. Lesions of low vascularity can only be recognised by DSA on the basis of vessel displacement. These lesions are not a primary indication for examination by digital angiography.
静脉内和动脉内数字减影血管造影能够显示耳、鼻和咽喉区域的高血管性肿瘤。在颈外动脉区域内，用于动脉内化疗的静脉旁路的直接穿刺没有风险，可用于评估肿瘤的可及性。低血管性病变只能通过数字减影血管造影根据血管移位来识别。这些病变不是数字血管造影检查的主要指征。
