CT stands for computerized tomography, and is also commonly called a CAT Scan. Since its introduction in 1974, CT has revolutionized medical care by providing detailed images of the body and disease processes. A CT scan uses an x-ray beam that rotates around a specific area in the body to generate a detailed image of the body’s internal structure.

Using a series of pictures, often called “slices,” CT imaging creates a three-dimensional view, clearly showing both bone and soft tissue. Slices refer to the number of images taken per rotation of the scanner – the higher the number, the more detail captured. With the ability to capture these advanced 3D images, CT scans can help reduce invasive exploratory procedures, such as surgery.
