Abstract
Abstract Computed tomography (CT) has become a valuable guidance modality for a large number of diagnostic and therapeutic percutaneous interventions. Diagnostic and therapeutic interventions guided by CT are among the most common interventional radiology procedures performed in clinical practice. Common diagnostic CT-guided interventions include tissue biopsies, fluid aspirations, and catheter drainages. Needle biopsies can be used to obtain tissue for cytologic or histologic assessment from almost any anatomical region of the body. Positron emission tomography (PET)/CT–guided diagnostic and therapeutic interventions have emerged recently and are increasing in frequency and number of indications. This chapter discusses common interventional procedures that are performed in both the interventional CT and PET/CT suites and outlines patient issues, procedural techniques, radiation/safety, and other clinical considerations that pertain to both interventionalists and anesthesiologists.
