In addition to serving as a diagnostic imaging modality, computed tomography (CT) is also routinely used to guide a variety of interventional radiology procedures such as percutaneous fine needle aspiration and core needle biopsies, placement of drains to remove fluid, thermal ablation of tumors as well as some nerve blocks and joint injections. Body imagers and interventional radiologists typically perform CT-guided interventional procedures. Compared to fluoroscopy, the advantage of CT-guidance is the detailed cross sectional visualization of anatomy in relation to the interventional tools.
CT-guided interventional procedures have some unique features compared to diagnostic CT, including repeated radiation exposure of a small part of the body during the same session with potential for skin injury, customized image acquisition protocols, large dose variations among the different procedures and challenging dose estimation methods.
An interventional radiologist will explain current clinical practice and provide the context for this session. Physicists with proven expertise in this area will then review and discuss issues and potential solutions for quality control, dose optimization, and assessment of procedure complexity.
Learning Objectives:
1. Illustrate the scope of CT-guided interventional procedures in clinical practice
2. Review current best practice recommendations for CT-guided interventional procedures
3. Discuss the challenges of radiation dose management for CT-guided interventional procedures
4. Detail approaches to the concepts of complexity and utilization for CT-guided interventional procedures
