Computed tomography (CT) and ultrasound (US) are currently considered as the the main imaging modalities in the field of interventional radiology. Because of the different characteristics of these modalities their use is different. In particular CT is widely used to obtain accurate needle-tip localization and excellent delineation of interposed vital structures but the most important draback is the lack of real-time imaging. On the other hand US is readily available, relatively inexpensive, and allows for real time imaging. Moreover, Color flow Doppler imaging can help identify the vascular nature of the mass and the adjacent vascular structures. In this chapter we will show the different Interventional Radiology Procedures by showing advantages and limits of these techniques.
