CT Scan
Computed Tomography (CT) is a diagnostic imaging procedure that combines the use of x-rays with computer technology to produce cross-sectional images (“slices”) of the body. The images produced are more detailed than those of an ordinary x-ray.
The Siemens Emotion 16 slice CT scanner is fast and safe. Furthermore, in always keeping the patient the priority, Siemens uses CARE Dose4D special software to lower the radiation dose as much as clinically possible, particularly for our pediatric patients.
Some common uses of the procedure are:
- Abscesses in the abdomen
- Appendicitis
- Colitis (inflammation of the colon)
- Cancers of the colon, liver, pancreas and kidneys
- Diverticulitis
- Lymphoma
- Pancreatitis
- Staging for cancer
THE CT SCAN:
- You will be lying flat on a table usually on your back, stomach or side.
- Depending on the study scheduled, you may be given an injection of intravenous contrast during the CT examination.
- The table will move slowly through the machine as the actual CT scanning is performed.
- You may be asked to hold your breath at different times during the exam.
- The actual examination time can vary from a few minutes to about an hour, depending on the procedure. However, the actual x-ray exposure time is minimal.
INSTRUCTIONS FOR THE PROCEDURE:
- Some CT studies require specific instructions, such as not eating or drinking anything for several hours before an exam or drinking an oral contrast material. Your doctor will inform you of these preparations. You can also call the Hastings Imaging Center and a technologist will advise you of the proper steps toward a successful exam.
- You should wear loose fitting comfortable clothing. You may be given an exam gown if any of the clothing interferes with the exam.
- You may be asked to remove any jewelry, eyeglasses, dentures and hairpins which affect the CT images.
- Patients must always notify the technologists of any possibility of pregnancy.
Intravenous Iodinated Contrast
In certain cases, the radiologist may determine that the usefulness of your CT may be improved by 
administering intravenous iodinated contrast.
Most patients experience no unusual effects from this injection other than some warmth or minimal flushing which is very common. As with the injection of any medicine or drug, however, a few risks are involved, most of which are mild and momentary: slight nausea, or a medicinal or metallic taste in the mouth. There can also be minor reactions such as itching, sneezing, or a few hives. Uncommonly, there can be more serious reactions.
IMPORTANT!
If you know of any allergies you might have to x-ray dye or iodine be sure to tell your doctor and alert the Hastings Imaging Center staff of any issues at the time you exam is scheduled.
