Computed Axial Tomography (CT Scan)
CT (or CAT) stands for Computed Axial Tomography. This technique uses an X-ray tube that rotates in a large circle around the patient sending a thin x-ray beam through the body that is detected by a large number of computer detectors located around the circle. The computer creates a cross sectional image of any plane in the body, in a sense dividing the body into thin slices, like a loaf of bread. The detail and contrast is far greater than conventional radiographs. The procedure is brief (about 20 minutes) and safe, but does require general anesthesia to keep patients absolutely still.
CT scans can show problems that cannot be seen with other diagnostic imaging. It is used for disorders of the head, neck, spine, joints, soft tissues and bone. For some conditions, the scan is performed after an IV injection of an iodine contrast agent to highlight vascular structures .
All images are read by a board certified radiologist.
