Physicians giving you a better view of your health


PET/CT What to Expect During the Procedure

To begin the procedure you will receive an intravenous injection of radioisotope in your arm or hand. This feels like a blood test. You will then relax in a reclining chair in a quiet, dimly lit room for 45-60 minutes to allow circulation of the isotope. We then ask you to lie on the table on your back. Next, our scan table slides through the large opening, sometimes called a “donut hole”, acquiring images for about 30 minutes. You will feel nothing and hear nothing, as this procedure is very quiet and easy to tolerate. No breath holding is required during this procedure.

PET/CT How Should I Prepare?

In preparation for this procedure we ask that you have nothing to eat 6 hours prior to this exam. You may have water (no coffee, no flavored water). We also ask that you stop all diabetic medications for 6 hours prior to exam. No cough syrups, cough drops or hard candy. A high protein, low carbohydrate diet is recommended 24 hours before exam. Please avoid strenuous physical exercise 24 hours prior to exam. Our scan room maintains a temperature of 70 degrees; it may be a good idea to dress warmly. You will not need to change into a gown.

What to Expect After the Procedure

Upon completion, you may resume normal activities. Hydrate well and empty your bladder frequently for 24 hours. Please avoid close contact with babies and pregnant women 6 hours following the exam. No driver is needed following this procedure. Reports will be sent to your physician within 5 business days. Contact your physician for any information pertaining to the findings.
