Popis: Cross-sectional imaging modalities such as ultrasound, computed tomography (CT), and magnetic resonance (MR) imaging are well-accepted guiding tools for interventional biopsies and therapies (Gupta and Madoff 2007). Especially CT combined with fluoroscopy is able to offer fast and safe ways to nearly any target in the human body, incorporating the major advantage of panoramic views compared with ultrasound, and therefore often represents the guiding modality of choice (Rogalla and Juran 2004). Even targets in bones and air-containing structures (e.g., lungs) can be addressed very easily and successfully with CT guidance. In contrast, MR imaging seems to be more complex and time-consuming and therefore is usually reserved for interventional procedures in very tricky areas with the necessity of high soft-tissue contrast and in situations where CT is contraindicated (Gupta 2004). The accuracy of the puncture and the complication rates depend on the target size and site, traversing and surrounding anatomical structures, the number of biopsies, the material and puncture technique selected, and patient’s cooperation (Gupta and Madoff 2007).
