Currently, there is a worldwide shortage of the contrast dye used in some imaging procedures. As a result, you may be contacted to reschedule your appointment. This contrast dye is necessary for accurate pictures, and it enables doctors to diagnose and treat diseases.
During this shortage, Allina Health is taking steps to conserve our supply of the dye while ensuring that all of our patients receive safe and appropriate care.
We anticipate this contrast shortage to last through at least June 30.
Computed tomography scans, also known as CT scans, not only give more diagnostic information to your doctors than an X-ray – they can also save precious exam time. A CT scan can rule out a major illness or give a swift diagnosis to get you started on a treatment plan to get you back on the path to feeling better.
What is a CT scan?
A computed tomography (CT) scan is an imaging method that uses X-rays to create cross-sectional pictures of the body.
Why it's done
These scans can help diagnose tumors, hemorrhages, head injuries and bone abnormalities. Inside the CT machine, the X-ray tube circles around the patient taking pictures as it rotates. These slices can be viewed two-dimensionally or added back together to create a three-dimensional image of a body structure.
