Fluoroscopy time -- used as a measure of cath lab radiation exposure -- could be improved by focusing on hospital and operator variables, according to Emory University research led by Dr. Reza Fazel. PCI and invasive angiography account for about 8% of medical imaging radiation exposure. "Yet, despite its importance, no national benchmarks for invasive coronary angiography and PCI fluoroscopy time ... have been previously developed," the authors wrote in Catheterization and Cardiovascular Interventions. They found modifiable factors explained 19% of fluoroscopy time variation for PCI and 17% for invasive angiography.
