When you need a PET scan, the best results are obtained by a medical center that does many scans on a weekly basis. Choose an imaging center that takes a comprehensive approach to imaging procedures. Scans use activated hydrogen atoms to provide images of the soft tissue of the body and are non-invasive. PET scans can provide images of any tissues that have water or are fluid based.
While most people can schedule their PET scan without preparation, some patients need to consider the effects of certain medical conditions on their scans. One condition to keep in mind is diabetes.
Possible Issues Due to Diabetes
The radiotracer used during the scan causes problems with the scan. High insulin levels can likewise cause a similar problem. Insulin levels can be high due to certain disease processes, such as an infection of the pancreas. The cause is not always diabetes. Regardless of the cause, a high insulin level needs to be reported to the center before your scan.
High blood sugar levels can also cause issues with a successful scan, as it can interfere with the ability of the scan to detect cancer cells. This can ultimately defeat the purpose of the scan, especially if it needs to search for cancerous growths or to support cancer treatments.
Diabetics with high insulin levels will also cause an issue with a PET scan. These diabetic patients will also give false readings when trying to detect cancer cells, even with a low blood sugar level.
Preparation is Necessary
When scheduling your PET scan, always inform the scanning center on every visit that you are a diabetic. Ask our staff for advice on how to keep your blood sugar levels low enough for a successful test. Through adequate preparation, your PET scan can go as smoothly as possible.
