Often called a CT scan, computed tomography is a medical treatment that combines X-rays and computer technology to provide comprehensive images of the inside components of the body. Patients recline on a table, and an X-ray machine rotates around them to take pictures of different body sections during the scan. A computer processes these pictures to create three-dimensional representations that help medical professionals diagnose disorders and develop treatment plans.
The entire CT scan procedure is typically painless and lasts about 30 minutes. It may begin with the administration of a contrast substance or the placement of an IV line. The contrast substance improves visibility for radiologists in specific areas. If contrast material is used, it will be delivered through any IV lines you have. Once the scan is complete, you can return home and resume your regular activities.
In most cases, the contrast material used in CT scans is well tolerated and shouldn't have any unfavorable consequences. It is crucial to let your doctor know if you have an allergy to iodine, though. so they can provide medicine to lessen the likelihood of an adverse reaction.
Some people may experience discomfort while lying on the table during the scan, but this is rare. You may also hear clicking and buzzing sounds as the X-ray machine moves around you, but most people do not find these noises bothersome. However, lying still for an extended period inside the compact CT scanner may cause anxiety or claustrophobia in some individuals.
