 We performed 3D-CT angiography (3D-CTA) with contrast injection to a feeding artery through a selectively introduced catheter into the intercostal artery in a patient with spinal hemangioblastoma. It revealed a relative three-dimensional (3D) anatomy between a tumor body,feeding arteries,draining veins,and surrounding vertebrae with superior resolution to 3D-CTA with intravenous contrast injection. This observation was used for preoperative planning facilitating tumor removal,through reconstructed 3D fly-through animation providing intraoperative identification and obliteration of feeding arteries. This examination was carried out without difficulty by utilizing IVR-CT/angio system (IVR: interventional radiology) which combines angiographic and CT equipment with a single fluoroscopy table,because it does not require a room-to-room transfer of the patient with the catheter left cannulated. DSA detection for any spinal lesions,neoplastic or vascular ones,is always better assisted by 3D-CTA with the IVR-CT/angio system (IVR-CTA).
