Cat Scans – Computed Tomography

One of the more common imaging tests used in diagnosing is computed tomography or CT (also called CAT) scans. The Toshiba Asteion VR Computed Tomography System used at VMH delivers images in half a second. The Imaging Services Department at VMH conducts about 117 scans per month under the guidance of lead technician, Tonya Rood. CT scans are similar to ordinary x-rays because they are produced when a beam of high-energy radiation passes through the body. A CT scan uses a pencil thin beam to create a series of pictures from different angles. 

This information is fed into a computer that calculates how the images overlap and shows a clear slice, or cross-section of the body. CT scans reveal both bone and soft tissues, including organs, muscles and tumors and is one of the best tools for studying the chest and abdomen. CT scans are an important tool in diagnosing head and spine injuries, lung and liver disease, cancer, tumors, blood clots, internal bleeding and other diseases and illnesses. For trauma patients, like auto accident victims, this technology can be lifesaving by providing better, more precise images.
