A CT scan, which stands for computed tomography, is an imaging procedure used to examine the internal structures of the body.
The images are produced by exposure to a controlled source of x-rays and processed on a special computer system. CT scans can be useful for diagnosing a range of different diseases and problems with the anatomy.
During a CT scan, you will lie on a flat bed while a tub rotates around you, taking images.
CT examinations are typically used for urological issues such as kidney stone detection, as a post-operative assessment following neurosurgery, for vascular reasons to show the arterial flow from the chest down to the feet, and to assist with planning ENT surgery. CT scans are also appropriate for patients who are not able to have MRI perhaps due to having a pacemaker.
When you leave the department, there should not be any issues that would prevent you driving or working normally. However any female patient who is, or might be pregnant, must notify the radiology department in advance of their examination, and all patients should inform the radiology department if they have recently had an x-ray investigation.
