Computed Tomography (CT) or "Cat Scan" technology uses X-Rays and computers to study cross-sectional images of your body. CT is commonly used to investigate head injuries, herniated discs, fractures, and changes in your organs.
Midwest Open Imaging's Siemens multi-slice CT is able to acquire numerous images of your body in just a few seconds. It means less time on the scanner and shorter breath holds, which increases patient comfort.
Midwest Open Imaging offers Walk-In CT appointments Monday-Friday from 8:30am-4:30pm (last check-in 4:15pm). If you need contrast for your exam, we ask that you not eat or drink anything 2 hours prior to your exam (see "Preparing for your CT", below). |

CT vs. MRI What's the difference? |
|
Patients sometimes confuse CT and closed MRI, as the machines look similar (see photos, below). But there are major differences between the two machines. While MRI images are generated using powerful magnets, CT images are created by combining X-Ray and a fast computer. CT is safe for patients with surgical implants, such as aneurysm clips and pacemakers, while MRI is not. CT is better at examining the body's organs and bone structure. MRI is superior at evaluating spines and soft tissue-- especially muscles and joints. Finally, from a patient-comfort standpoint, CTs are very quick exams (usually 10 minutes or less), while MRIs often take 45 minutes or longer. |

A word about CT contrast Indications & Precautions |
|
Depending on the exam, MWOI's radiologist guidelines may recommend the use of barium- or iodine-based contrast. The contrast highlights structures, leading to better visualization and diagnosis of abnormalities-- especially in cases where cancer is suspected.
SPECIAL CONSIDERATIONS re: IV CONTRAST
1.) If you have a known allergy to contrast, iodine, or shellfish, please consult with your ordering physician and Midwest Open Imaging staff before your CT exam.
2.) All CT contrast patients 60 & older or diabetic must have BUN/Creatinine levels checked within the last 3 months.

Preparing for your CT To eat or not to eat |
|
Many CTs require what we call "prep," which often includes abstaining from food & drink (NPO) and/or drinking a contrast solution after you arrive for your appointment. Our schedulers will detail your prep over the phone, or you can use the list below as a general guideline. Most contrast CTs require a period of no food or drink (NPO) two hours prior to your exam.

Contraindications for CT Your pre-scan safety check |
|
Midwest Open Imaging's multi-slice CT offers an optimal combination of low radiation exposure and short exam times. However, pregnant women, or women who think they could be pregnant, should avoid having a CT scan.
Additionally, if you have a known allergy to contrast, iodine, or shellfish, please consult with your healthcare provider and Midwest Open Imaging staff before your CT exam.

What to expect during your CT Comfortable. High Tech. |
|
Midwest Open Imaging's technologists are trained to make your CT as comfortable as possible. One of our techs will be able to hear and watch you at all times. Most CTs take 10 minutes or less. A comfortable table will slowly move through the scanner's opening, while the tech gives you direction by intercom. Depending on the exam, you may be asked to hold your breath for a moment. Your healthcare provider may ask us to administer an oral or IV contrast, which helps the radiologists better visualize the study. If you have a known allergy to contrast, iodine, or shellfish, please alert Midwest Open Imaging staff before your CT exam.
