A CT scan (computed tomography scan) is a diagnostic test where a series of X-rays are taken and combined to create a picture of a cross-section or slice of the body. With a CT scan, doctors can see bones and soft tissue. The images can be taken of almost any part of the body and used to diagnose a variety of medical conditions including cancer, bone fractures, blood clots, and more.
There is radiation exposure during a CT scan, so if you are pregnant or suspect you might be pregnant, please speak with your doctor before undergoing this exam.
What You Need To Know Before Your Exam
