Radiology is basically a specialty in medicine that uses imaging in the diagnosis and treatment of disease. A variety of imaging techniques are employed by radiologists. Ultrasound, x-ray radiography, CT scanning, MRI, and PET are all used in treatment and diagnosis of disease. Interventional radiology is a term used to refer to the use of imaging technology to guide one in performing medical procedures.
The Royal College of Radiologists, a charity that is registered, exists to advance the practice and science of radiology. The body comes up with standards to be used by those providing radiological services. They provide such standards in documents that are less of regulations and more of suggestions on practices that will facilitate provision of high quality imaging services.

Surgery that requires implants has been seen to be quite risky. This is especially in relation to retention of instruments and sponges. Past policies insisted on use of instrument counting as a means to avoid this. However, further research has shown that radiology is a better fit for the task. It is more comprehensive and also rids the precautionary measure of human error.
Though the research is somewhat flawed, it gives a vague idea of how grim the situation is. The past policy should therefore be revised to add radiology to the list of procedures carried out to ensure that no instruments are left inside a surgical site.
