Overview of Computerized Tomography (CT) Scans

CT Scans Versus MRI Scans

Computerized tomography scans do not produce as much detail as magnetic resonance imaging scans. However, they are less expensive to perform and used more often. They are also faster, which is often why they are performed in emergencies. A computerized tomography scan uses a large doughnut-shaped machine the patient slides into on a special table. The computerized tomography machine has a much larger opening and is not as deep as a magnetic resonance imaging machine. This makes sedation less necessary for some patients.

Doctors will provide their recommendation on which scan is necessary and when. In most cases, computerized tomography scans are the choice for head trauma or a bone fracture, as well as for a general image of internal organs. Magnetic resonance imaging is employed when doctors need a detailed image, such as in the case of a herniated disk or soft tissue problems.
