A radiograph is a quick and painless investigation used to visualise the inside of your body by exposure to radiation (X-rays). Although in vascular surgery they have largely been superseded by the greater information attained from a CT or MRI scans there remain occasions where a standard radiograph provides sufficient information to guide further investigations and/or treatment e.g. bone infection (osteomyelitis), thoracic outlet syndrome caused by an additional (cervical) rib. In addition, radiographs are often incorporated into follow-up surveillance protocols for patients in who a stent has been inserted e.g. endovascular aortic aneurysm repair (EVAR).
