Description
Noninvasive cardiac imaging has become a critical pathway for diagnosis and risk assessment in patients with known or suspected ischemic heart disease. Low-level ionizing radiation is used in most of these procedures like radionuclide myocardial imaging and cardiac CT scanning. There is lack of any direct data which indicates the occurrence of any radiation-related adverse events with these diagnostic tests. However, recent concern has been raised due to the cumulative dose of radiation that patients receive during these procedures. Efforts are underway to help reduce the radiation exposure while preserving image quality for accurate interpretation and avoidance of repeat testing. This review will focus on the various advancements and methods to reduce the radiation dose in patients undergoing nuclear myocardial perfusion imaging and cardiac CT scanning.
