Norwalk Radiology Consultants

When applied to cancer, PET/CT scans are performed to:

​

• Detect the presence of cancer.

• Determine whether a cancer has spread to other sites within the body

• Assess the effectiveness of treatment.

• Determine any return of cancer after successful treatment.

​

Once scheduled for a PET/CT, our office will call you and give you detailed instruction on how to prepare for your exam.

​

General guidelines are as follows:

​

• Please arrive 30 minutes prior to your scheduled injection time.

• Drink plenty of water, an extra glass or two, to ensure proper hydration (plain water only, no sports drinks or flavored water).

• Do not eat anything for 6 hours prior to your scheduled appointment. This includes chewing gum, candy and mints.

• Avoid caffeine (coffee, cola, tea) for at least 12 hours before your exam.

• Refrain from vigorous physical exercise for at least 24 hours prior to your appointment.

• Regular prescribed medication can be taken as usual with water.

• Please leave valuables such as jewelry and watches at home as they cannot be worn during the examination.

• Please wear comfortable loose-fitting clothing that has no metal.

• Women should wear a sports bra that has no metal, if possible.

• If you have diabetes, please notify our office prior to your scheduled appointment. We want to avoid high or low glucose levels.
