CT exams gather a series of images of the body from different angles. This non-invasive exam provides anatomical information quickly and accurately, which assists your physician in making accurate diagnosis and treatment recommendations. Lexington Medical Center offers 24-hour, state-of-the-art, helical computed tomography (CT) with a skilled technologist and radiologist available at all times.
CT testing is available for emergency trauma evaluation; severe headache or stroke; acute abdominal pain such as appendicitis and kidney stones; and for evaluation of pulmonary embolism. It’s also a vital tool for the workup and monitoring of cancer patients, and for evaluation of complex fractures, visual problems, sinus disorders and lung diseases.
64 Slice Dual-Source CT Scanner
Our Radiology Department is home to an advanced Siemens 64 slice dual-source CT scanner. The scanner has two sets of X-ray tubes and detector arrays in a single CT gantry. The extra imaging power speeds up the scan process which makes it a highly effective imaging option in emergency and acute care situations. Also, the scanner performs CT angiography to help physicians evaluate the arteries, assess their function, observe anatomy and detect the degree of coronary of heart disease.
How do I prepare?
Different tests require different preparations. You shouldn’t eat for at least four hours before your scan. While you can expect to be in the PET/CT center for 1-1/2 to 3 hours, the actual scan takes much less time. You may be asked to drink an oral contrast agent approximately 90 minutes before your scan. For a short time, you may feel a slight warm sensation in your body. This is normal.
What should I expect?
The CT machine looks like a large square doughnut and only covers the area that is being examined. Before entering the scanning room you will be asked to remove anything metallic. Once you’re positioned on the table, the scan will begin. During the exam you will be in the room alone; however, your technologist will be able to see and hear you throughout the whole procedure. There are no side effects from the contrast agent so you can return to normal activities after your scan.
