Proper training, understanding factors influencing radiation dose, and using dose reduction techniques can effectively manage patient radiation dose during fluoroscopic procedures.
What are the issues and management strategies for patient radiation exposure during fluoroscopic procedures?
Effective management of patient radiation exposure during fluoroscopy requires regular equipment assessment, direct clinical monitoring, and application of specific dose reduction techniques by trained operators.
Fluoroscopic procedures (particularly prolonged interventional procedures) may involve high patient radiation doses. The radiation dose depends on the type of examination, the patient size, the equipment, the technique, and many other factors. The performance of the fluoroscopy system with respect to radiation dose is best characterized by the receptor entrance exposure and skin entrance exposure rates, which should be assessed at regular intervals. Management of patient exposure involves not only measurement of these rates but also clinical monitoring of patient doses. Direct monitoring of patient skin doses during procedures is highly desirable, but current methods still have serious limitations. Skin doses may be reduced by using intermittent exposures, grid removal, last image hold, dose spreading, beam filtration, pulsed fluoroscopy, and other dose reduction techniques. Proper training of fluoroscopic operators, understanding the factors that influence radiation dose, and use of various dose reduction techniques may allow effective management of patient dose.
