Interventional procedures - what patients need to know

» Which procedures are associated with higher radiations doses?

Interventional procedures - angiography, cardiac catheterisation and Computed tomography (CT) -can be associated with higher doses of radiation with doses that are about 100 to 1000 times higher than that delivered during a chest X ray.

» What are the possible effects of radiation exposure from interventional procedures?

The typical dose of an interventional procedure brings a one in 10 000 risk of skin injury and a small increased probability of cancer in future years. In most situations, skin injuries can be prevented by using the proper technique. An interventional procedure performed under X ray fluoroscopy guidance often replaces a more invasive surgical procedure. 

» Should I be concerned about radiation if my child has been prescribed an interventional procedure?

As part of the justification process, doctors determine whether the benefits of the procedure outweigh the risks. The doctor should be able to explain why your child needs the procedure and why other procedures are not suitable.
