CT (Computerized Tomography) scans are painless diagnostic tests that use conventional X-rays. A series of pictures is reconstructed by a computer into cross-sectional views, allowing physicians to see inside areas that cannot be seen in conventional X-ray images. Due to recent advances in CT technology, physicians can detect many conditions - and start planning necessary treatment - much earlier than ever before.

Rapid City Regional Hospital has three CT scanners and is one of the first imaging facilities in our region to use the multi-row GE Lightspeed Plus™ scanner. This advanced technology delivers superior patient care and enhanced diagnostic confidence. New clinical procedures, such as multi-phase abdominal and CT angiography exams, can be performed with this cutting-edge technology and at a speed much faster than conventional CT scanners.

CT scans have become the most commonly used tool in the imaging arsenal. Other than a few exceptions (breast diagnosis, obstetrics and soft tissue structures in joints), CT is most often the procedure of choice.

CT scans are also used to perform a coronary artery scan, or Heart Score. This test is a non-invasive, effective, and safe way to detect coronary artery calcification in a matter of minutes.

The risks from CT scans are minimal. However, CT scanners do use X-rays. If you are pregnant, or even think you might be, it is important to notify your physician.

Each CT exam is individualized and tailored to each patient's needs. Most exams last about 15 minutes. Many exams require the injection of a contrast agent through an IV during the procedure. This advances the scan images.

During the procedure, the body part being scanned will be positioned in the middle of the large doughnut-shaped opening, or gantry, which holds the X-ray tube and an electronic detector. You won't feel a thing during the procedure but may hear some noise and the table may move to make adjustments for a better view.

It is important to lie very still throughout the procedure. At some points, you may be asked to briefly hold your breath.

Rapid results are essential not only for your peace-of-mind, but also for your physician to begin planning any necessary treatment. Experienced radiologists will read the scans and forward the results to your physician usually by the next business day.
