title: [Inspection of dose reduction in patients during percutaneous coronary intervention and catheter ablation procedures].
abstract: With an increasing number of interventional radiology (IVR) procedures, it is a critical issue to control and reduce the radiation dose for patients by radiological technologists. In our study, we analyzed the usefulness of a provision for radiation reduction on catheter ablation and percutaneous coronary intervention (PCI) procedures based on the data from radiation information system (RIS). With regard to catheter ablation, 50% reduction was enabled with decreasing fluoroscopic and radiographic conditions regardless of each technique. Radiation reduction enabled a decrease in the fluoroscopic dose during PCI procedure. However, note that excessive radiation reduction does not show positive results of the radiation dose reduction. Moreover it leads to an increase in fluoroscopic time.
