Computed Tomography

Computed Tomography (CT) uses X-ray technology to take pictures of the interior of the body in cross-sections or “slices.” Advanced computer software puts the “slices” together to give a complete picture of the anatomy. Rush-Copley utilizes spiral CT scanners that offer 4 and 64 “slices” for the fastest, clearest images.

CT is a painless, non-invasive test used to image bone, soft tissue and blood vessels. It is particularly helpful in the diagnosis of cancers, cardiovascular disease, infection, trauma and musculoskeletal disorders and can replace exploratory surgery and surgical biopsy in many cases. It is fast and accurate, especially in cases of trauma when time is of the essence.

During the test the patient lies still on a table which gradually moves into the CT scanner. The motion can be very slight and nearly undetectable by the patient. Some exams require the use of contrast material to enhance the visibility of certain structures. The contrast material may be injected intravenously (IV) or by enema depending on the exam.

CT is a versatile diagnostic tool to:

  • Study the chest and abdomen to identify cancers of the lung, liver and pancreas
  • Measure the size and location of a tumor and its affect on neighboring tissues
  • Guide physicians during biopsies and brachytherapy
  • Detect vascular disease
  • Visualize maxillofacial structures

Risks of CT:

  • Women should inform medical personnel if there is any possibility of pregnancy. CT scanning uses X-rays to produce the image.
  • Nursing mothers who require an exam with contrast injection should wait 24 hours after the exam before resuming breastfeeding.
  • Patients who are allergic or have certain medical conditions may not be candidates for the contrast exam and should disclose their conditions prior to the test.

Advanced technologies now available at Rush-Copley:

CT Heart Score

Cardiac CT for calcium scoring visualizes the location and amount of calcified plaque in the coronary arteries. The presence of calcified plaque indicates the likelihood of coronary artery disease. The cardiac CT may also indicate aortic aneurysm or other abnormalities that are not causing symptoms. The results of the test help doctors determine the best course of action.

Virtual Colonoscopy

Colon cancer is the second most deadly cancer in America, but it is highly preventable if detected early. Unfortunately, the discomfort of traditional colonoscopy is a deterrent to regular screening. Virtual Colonoscopy quickly, painlessly and without sedation, examines the colon for abnormalities. In less than 15 minutes, it can provide clear and precise images of the colon, enabling radiologists to look for polyps, which may be precursors to cancer. This screening requires only a simple preparation taken orally the day before. After the scan, patients can return immediately to their normal routine.

Cardiac CT Angiography

Cardiac CT Angiography (CTA) is a new and revolutionary method of visualizing the inside of the coronary arteries.  With the latest advances in high resolution scanning, the 64-slice CT scanner can create detailed and accurate images of the heart, lungs, and arteries in just seconds. Cardiac CTA is a highly accurate alternative to Cardiac Catheterization for those people who have an abnormal stress test but are unlikely to have significant heart disease. In people with nondiagnostic stress tests, or those with “negative” stress tests but who are at high risk of coronary artery disease, Cardiac CTA can quickly and non-invasively determine whether significant coronary artery disease is present.
