A Computed Tomography (CT) scan is usually recommended to diagnose internal injuries, cancers, internal bleeding, traumatic injuries that concern muscles, bones, and tissues. Compared to an X-ray, a CT scan gives clearer results and allows the doctor to make an accurate diagnosis for many concerns. Many Boise body imaging centers rely on multi-slice CT technology, which is an advanced way to get clear images of the body part within seconds. If you are going for a CT scan for the first time, here’s what to know before, during, and after the test.
Before a CT scan
Ensure that you wear comfortable clothes. You will be asked to remove all metal objects from your body, including jewelry, and will have to change into a hospital gown. In some cases, patients are advised against drinking or eating anything for a few hours before the CT study. For CT studies, it may be necessary to use an oral contrast material. You may also need IV contrast, which allows for better images.
During the CT scan
Your technologist will ask questions about your medical history and whether you are allergic to x-ray dyes or contrast materials. If IV contrast has been ordered, they will administer the same. During the scan, you will lie down on a table, which will go forward and back under a machine that almost looks like an archway. The device will emit X-rays that will help capture images of your body, which are then used in a computer to get the final images. You may have to adhere to breathing instructions as requested by the technologist.
After a CT scan
You have no restrictions after a CT scan and can return to everyday life. You may have to drink lots of water and fluids to pass the contrast material through urine. You can also drive back home and eat normally. It may take a couple of days to get your final CT scan report, which will be first evaluated by a radiologist and sent to the healthcare provider.
Final word
Computed Tomography (CT) scans do expose patients to radiation, but there are no long-term side effects known to that. If you still have any concerns, know that you are pregnant, or expect to get pregnant, talk to your doctor and ensure that you know all details. If required, your doctor may order other tests or recommend an X-ray if that is enough for the diagnosis.
