**8.6 Digital subtraction angiography (DSA)**

DSA is used in preoperative phase to identify the feeder vessel and its preoperative embolization. Selective vessel angiography in DSA allows to determine the exact branch(es) supplying the tumor and its selective embolization. JNA shows a characteristic *'tumor blush'* in DSA of external carotid artery. This can also help in predicting the expected blood loss during tumor resection [35].
