Images in a 72-year-old man with a lower gingival cancer with multiple tumor feeding arteries. A, DSA and (B) intra-arterial cone-beam CT obtained in the selective facial artery. C, Preinterventional enhanced CT image at the same level. D, DSA and (E) intra-arterial cone-beam CT obtained in the selective masseteric artery. F, Preinterventional enhanced CT image at the same level. G, DSA and (H) intra-arterial cone-beam CT obtained in the selective inferior alveolar artery. I, Preinterventional enhanced MR image at the same level. Preinterventional enhanced CT and MR imaging studies (C, F, and I) show a deeply invasive tumor with destructive lesion of jawbone. DSAs (A, D, and G) obtained from the multiple tumor feeders show only faint stains, and, therefore, it was difficult to understand the vascular territory of each artery. The cone-beam CT (B, E, and H) allowed the interventional radiologists to identity the tumor stains (arrows) by a combined inspection with preinterventional CT or MR imaging studies and to determine the amount of antitumor agent for each feeding artery with confidence.
