[Digital subtraction angiography in oncologic diagnosis]

Digital subtraction angiography has become a safe, accurate and reproducible means of evaluating the vascular system. It offers the possibility of obtaining high quality vascular images at very low intravascular iodine concentrations. In oncology, digital subtraction angiography is performed in preoperative visualization of the vascular supply of tumours, in planning and control of liver-port-systems and evaluation of complications following radiation therapy or chemotherapeutic measures. DSA has widely replaced film angiography in vascular imaging.
