Computed Tomography (CT)
CT scans are a noninvasive, painless radiological examination that is useful in diagnosing diseases and medical conditions in internal organs, bone, soft tissue and blood vessels. CT scans generate much more clarity than a typical x-ray since it produces multiple images from inside the body creating a cross-sectional view of the area imaged. An iodinated contrast material is often used to make structures and organs easier to see. The contrast can be used to check blood flow, find tumors, and look for other problems. Dye is injected in the vein and you may drink the oral contrast for some tests. CT images may be taken before and after the dye is used.
It is especially helpful in diagnosing cancer, heart disease, infectious process, trauma or bone related problems. It is often the preferred exam for studying the chest and abdomen because of the detailed pictures created by the multi-sliced views. Radiologists can confirm cancers, such as lung, liver and pancreatic, and can accurately determine the size, location and extent of involvement.

One of our specialty exams includes virtual CT Colonoscopy used to help screen patients for colon cancer.
Colon cancer is the second most common cause of cancer-related deaths in both men and women; however if detected early, colon cancer can be prevented. Screening can be performed between ages 40-50. Recently we have introduced CT Colonography which uses multidetector CT images with use of virtual computer software which allows us to look inside the colon. Some of the advantages of CT colonoscopy includes:
- Faster and less invasive than conventional colonoscopy
- Whole study takes only 10-15 minutes
- No sedation
- Very high success for detection of polyps and cancer greater than 10 mm
- Requires low dose radiation
Preparation for a CT colonoscopy Exam:
You will be instructed to follow a two day low residual diet in conjunction with a 24 hour bowel prep kit available from the pharmacy. More detailed instructions will be provided to you by the scheduler when you make your appointment.
CTC is not covered for screening test. If you are having this test because of symptoms related to your colon, your insurance may cover the exam. For people without symptoms, you should expect to pay $500.00 for the exam at the time of service.
