What is the radiation dose from interventional radiology procedures (catheter based such as cardiac cath, angiography, and angiograms)?
Interventional radiologic procedures use diagnostic-type imaging equipment to assist a physician in the treatment of a patient’s condition. These procedures frequently provide favorable medical results with minimal recovery time. In some cases these procedures avoid the need for conventional surgery or improve the prospects for a favorable outcome from surgery. As with any medical procedure, there are associated risks and the nature of these risks depend on the procedure. With interventional radiology procedures using X-rays, the level of risk depends on the type of procedure because some use very little radiation, while complex procedures use much more. In general, the risk of developing a cancer from the exposure is not a major concern when compared to the benefits of the procedure. Many of the complex procedures, such as ones used to open a partially blocked blood vessel, repair a weak area of a bulging vessel, or to redirect blood flow through malformed vessels, use extensive radia
