CT scans the body quickly and accurately, including the pelvis and areas near the pelvis. The test can be used to diagnose or detect the following:
Wear loose-fitting, comfortable clothing to your exam. For the procedure, you may need to change into a gown.
Metal objects, such as jewellery, eyeglasses, dentures, and hairpins, can interfere with CT images. Leave them at home or take them off before your exam. Some CT scans will necessitate the removal of hearing aids and removable dental work. Women will be required to remove bras with metal underwire. If possible, you should remove any piercings.
If your test will use contrast material, your doctor may instruct you not to eat or drink anything for a few hours before the exam. Inform your doctor about all medications you are taking, as well as any allergies you may have. If you have a known allergy to contrast material, your doctor may prescribe medications (usually a steroid) to reduce your chances of having an allergic reaction. Contact your doctor well in advance of your exam date to avoid unnecessary delays.
Inform your doctor of any recent illnesses or other medical conditions, as well as any family history of heart disease, asthma, diabetes, kidney disease, or thyroid problems. Any of these conditions may increase the likelihood of a negative effect.
The technologist starts by placing you on the CT exam table, usually on your back. Straps and pillows may be used to help you maintain the correct position and remain still during the exam. When you enter the scanner, the x-ray beam rotates around you. The rotating x-ray beams will not be visible. Because movement causes blurred images, you must remain still during the exam. You might be instructed to hold your breath for brief periods of time. The scan should take no more than ten minutes.
Many scanners are fast enough that children can be scanned without sedation. Sedation may be required in some cases for children who cannot sit still. Motion can cause image blurring and degrade image quality in the same way that it does in photographs.
The hard table may cause discomfort for some people.
Contrast given via IV may result in:
A mild burning sensation
In the mouth, there is a metallic taste.
Warm flushing throughout the body
Following the CT scan, you will be able to resume normal activities. It is advised that you drink plenty of water to aid in the removal of the contrast material from your body.
Your images will be analysed by a radiologist, and a signed report will be sent to your referring physician. Generally, your doctor will notify you of the results.
