Computed Tomography (CT) Scan

A CT scan is a painless method of taking a series of special pictures of your body. You will be asked to lie on a special table and the radiographer will position you for the examination. You may have to receive an intravenous contrast solution during the examination.

64-Slice CT Scan

OSF St. Francis has enhanced its medical imaging department with a new 64-slice computed tomography (CT) scanner, offering significant benefits over its earlier counterpart, the 16-slice CT.

What is 64-slice CT?
CT scanning allows for 3D x-ray images from different angles around the body. 64-slice CT is significantly faster than the 16-slice CT and allows for more accurate imaging and additional tests.

What are the benefits of 64-slice CT?

• Faster scan times allow physicians to capture a high-resolution image of the heart in less than 5 seconds. A scan of the whole body takes about 30 seconds.


• The procedure is non-invasive and pain free. Faster scan times mean patients do not have to hold their breath or lie still for as long as was required with 16-slice CT, a particular benefit for those with breathing problems or neck or back pain.


• The new technology may be an appealing and effective alternative to conventional, more invasive angiogram and cardiac catheterization


• Faster scan times mean less radiation exposure

When is 64-slice CT used?
64-slice CT can be used to detect blockages coronary artery disease, risk of heart disease and congenital heart problems. Because of its speed, it can virtually "freeze" the heart mid beat for accurate, anatomically correct 3D images. It can also detect blood clots in the lung and is being used is being used in diagnosis of early-stage cancers, as well as detecting neurological disorders, strokes, head injuries, herniated discs and bone fractures.
