Our Computed Tomography (CT) is a 40 multislice scanner which allows us to do Radiotherapy planning and other radiological diagnostic imaging investigations.
What is Computerized Tomography (CT) Scan?
CT is a type of imaging that uses x-rays and a computer to construct pictures (images) of the tissues in your body. Images of your body tissues are taken in a very small slices or spirals of information over a short period of time.
What does this examination entail?
CT scan is painless. You will lie on the firm table that moves inside the doughnut-shaped CT scanner. The table will move into the open center of the doughnut as the x-rays are being taken. In order to obtain the best images possible, you will be asked to lie very still during the scanning and you may have to hold your breath for a brief period.
How long will the examination take?
Most CT scans take about 20 minutes.
Are there any risks to having a CT Scan?
A CT scan is a very low risk procedure but there are some things that you would need to let your doctors know or X-ray staff before having a CT scan:
• If you might be pregnant
• If you are allergic to iodine
• If you are diabetic
• If you have high blood pressure
• If you have kidney disease or have only one kidney
• If you have congestive heart failure
• If you have had any problem with examinations with contrast or other contrast exams in the past
• If you are currently undergoing chemotherapy or have had recently received chemotherapy recently
What is the type of contrast?
Most patients having abdominal or pelvic CT scans will be asked to drink contrast media prior to scanning. This will “coat” the stomach and intestines to highlight them during scanning. Most patients may have some side effects from drinking the oral contrast. If the contrast media is white you may note white flecks in your stool for a day or two after scan.
Intravenous (IV) Contrast:
Depending on your symptoms and the part of the body to be scanned, an intravenous injection of the contrast will be administered. It is advisable that you fast a few hours before the exam. The contrast may cause you to have a slight nauseous sensation but this is only transient.
The contrast will be exerted via your kidneys. It is advisable to drink plenty of fluids after the examination.
This contrast is given rectally in order to highlight the rectum and lower portion of the large intestine. It is similar to an enema but with minimal discomfort.
*Please Note: You may receive more than one type of contrast.
