Q: How have radiation exposure and patient dose changed in cardiology over the past decade?
A: The short answer is that both have decreased.
In the past several years, patient doses and personal exposures in cardiology have shown a decreasing trend. This is very encouraging as many cardiologic procedures that are complex and require prolonged fluoroscopic guidance are becoming routine. There are several reasons for the decreases in both patient doses and personal exposures in cardiology. Some of these reasons involve technological advances and some changes in practice due to increased awareness of radiation exposures:
■ Conversion from image intensifiers (IIs) to flat-panel detectors (FPDs)
■ Increased use of pulse fluoroscopy
■ Changes in the use of filtration of the x-ray beam
■ Changes in protective apparel
■ Consciousness-raising education for both personnel and patient radiation protection
■ Increase in institutional requirements for education before granting privileges
■ National campaigns such as Image Gently® and Image Wisely®
