What is a CT Scan?
Computed tomography (CT) combines the use of X-rays with the latest computer
technology. Using a series of X-ray beams, the CT scanner creates cross-sectional images.
A computer reconstructs these “slices” to produce the actual pictures. Considering that
some slices are as thin as half a millimeter, a CT scan offers much more image detail than a
traditional X-ray — which means your doctor gets the best information to make the most
accurate diagnosis.
Why a CT scan?
Your doctor may recommend this type of diagnostic imaging procedure when there is a need to
evaluate soft tissue, such as internal organs. Because the system is able to capture
information in a cross-sectional format, your doctor is better able to view the size, shape and
position of soft tissue structures than if using regular X-rays. CT exams help identify tumors
and cysts, as well as help diagnose diseases of the liver, lungs, coronary arteries and other
internal organs.
