What is CT? Computed Tomography (CT) or "CAT Scan" technology uses X-Rays and computers to study cross-sectional slices of your body.  CT is commonly used to detect strokes, head injuries, herniated discs, fractures, and changes in organs and blood vessels. The Benefits of CT Midwest Open Imaging's SOMATOM multi-slice CT is able to acquire numerous images of your body in just a few seconds.  It means less time on the scanner, shorter breath holds, and less exposure to X-Ray radiation.  The scanner also has advanced imaging capabilities, including 3D reconstruction. How is CT different than MRI? Patients sometimes confuse CT and closed MRI, since the machines have a similar look.  But there are two major differences between the modalities:  the technology used to generate the images, and the types of images achieved.  CT uses X-Rays to create images, while MRI uses a magnetic field.  CT is better suited at examining organs, blood vessels, and bone structure.  MRI is superior at evaluating soft tissue, especially muscle and joint injuries.  In addition, CT is very quiet, whereas MRI scanners tend to be noisy. What to expect during your CT A comfortable table will slowly move through the scanner's opening, while the technologist gives you direction by intercom.  Depending on the exam, you may be asked to hold your breath for a moment.  The total exam should take less than 15 minutes.  As with conventional X-Ray, CT exams are totally painless.  Depending on the order, your physician may ask us to administer a barium or iodine contrast.  This helps our radiologists better visualize the study.  If you are diabetic or are allergic to iodine, please consult our staff before your exam.
