Guide To Positron Emission Tomography Scans (PET Scans)

PET Scans And Diabetes

Diabetes patients are still able to undergo positron emission tomography scans. However, these individuals will need to follow alternative instructions before their scans, and often afterward as well. This is because the normal instructions can interfere with the patient's blood sugar. Of course, as all individuals with diabetes know, managing their blood sugar is vital. Patients must consult their doctor before a positron emission tomography scan for instructions that are specific to their needs. There are, though, some common ones.

In most cases, diabetes patients will be asked to take their normal insulin dose. They will also consume a light meal four hours prior to their positron emission tomography scan. After the scan, diabetes patients typically follow the same procedure as other individuals. However, their doctor will tell them if they need to do anything different.

PET Scans And Claustrophobia

The machines used for positron emission tomography scans often trigger claustrophobia for patients. They are enclosed, which is not great for individuals with a fear of small spaces. The symptoms of claustrophobia during one of these scans include chills, sweating, excessive fear, nausea, dizziness, feeling faint, and an increased heart rate.

Thankfully, patients who are concerned about feeling claustrophobic during this scan can manage this reaction. Patients can choose to listen to music in certain cases, which allows them to focus on the lyrics instead of the scan. Deep breathing can help as well. In serious cases, some patients can receive mild sedative medication to keep themselves calm during the scan. Doctors will prescribe and administer this medication as needed.
