What is a CT Scan?

 

A computed tomography scan is a test that takes a series of X-rays of your bones and a computer constructs these images into cross sectional views displayed on a monitor.  The CT scan shows in detail a specific plane of involved bone and can reveal tumors of the soft tissue, or injuries to the ligaments, and tendons.  The CT scan can be used to identify the location and extent of fractures in areas difficult to evaluate.  A contrast dye may also be used, which helps improve the resolution and accuracy of the images.  Before the test you do not need to fast unless contrast dye is ordered.  The test takes approximately one hour to complete and the patient must remain still the entire time.  During the test the patient lays on a special table and the head of the table is moved into the scanner.  If contrast dye is used the patient may have a warm flushed feeling, and may experience a headache or nausea.  All of these reactions are normal and last for a short period of time.  After the test the patient may resume normal activity.  If contrast dye was used the patient will be monitored for a delayed allergic reaction and will be encouraged to drink plenty of fluids to help eliminate the dye from the body.
