Optimizing patient radiation dose in intervention procedures

Although numerous patients derive great benefit from interventional procedures, a serious disadvantage associated with interventional procedures is patient radiation dose. Therefore, interventionalists should be aware of how to reduce the radiation dose to their patients. Currently, no conclusive method for reducing radiation dose is available for interventional procedures; hence, it is necessary to combine various methods. In addition, in order to reduce the radiation injury risk in interventional procedures, evaluation of patient radiation dose is essential. Generally, the tradeoff for a decrease in radiation dose is a loss in image performance. Therefore, optimization of radiation dose and image performance is important in interventional procedures.
