[Prevention of radiation damage in interventional radiology (IVR)]

With the development of interventional radiology, radiation protection has become increasingly important for both patients and medical staff in interventional radiology. Sometimes, long fluoroscopy times and repeated angiography lead to higher radiation doses, limited to a small area of the patient's skin surface. This becomes the potential for deterministic effects of the skin and also may lead to an increased risk of stochastic effects. The entrance skin dose and effective dose can be deduced from the dose area product. It should be noted that minimizing patient dose leads to reduction of staff dose. Here we briefly explain radiation protection in interventional radiology.
