Learning Objectives:

To review radiation risks to healthcare workers and patients during digital subtraction angiography (DSA) and computed tomography (CT) guided interventional procedures, including Yttrium 90 (Y-90) radioembolization procedure and demonstrate updated tips and techniques for reducing radiation exposure.

Background:

Interventional radiology (IR) comprises fluoroscopic and CT guided therapeutic and diagnostic procedures. These are complex procedures and result in high radiation exposures to both personnel and patients. A good knowledge of equipment is essential for an effective optimization of radiation protection. Many interventionists are not aware of the potential for radiation injury from procedures, their occurrence or the simple methods for decreasing their incidence. Many patients are not being appropriately counseled on the radiation risks, nor followed up for the onset of injury, when radiation doses are high from difficult procedures.

Clinical Findings/Procedure Details:

A. Applied radiation physics and concept of ALARA.
B. Biological effects of radiation (stochastic & deterministic).
C. Radiation monitoring and documentation.
D. Guide to DSA/CT settings and newer features (knobology).
E. Standard precautions/techniques during IR procedures.
F. Special situations and precautions/techniques (pregnancy, pediatric patients, large patient and complex procedures especially Y-90 radioembolization.

Conclusion and/or Teaching Points:

This exhibit will review –
A. Applied physics relevant to fluoroscopic (especially DSA) and CT procedures.
B. Radiation risks from interventional procedures, including Y-90 radioembolization.
C. Radiation monitoring and documentation.
D. Updated standard and special techniques to reduce radiation exposure.
