PET/CT Research

If you are, or there is a chance you are, pregnant or if you start breastfeeding, please call the PET/CT department in advance of your scan day: 401-444-7777.

If at all possible, avoid unnecessary or prolonged contact with young children and pregnant women for 8 hours after your scan has been completed.

The Day Before Your PET/CT Scan

It is important that you stay well hydrated. Unless you are on fluid restriction, please drink at least eight glasses of plain water.

All medications may be taken as prescribed by your doctor.

The day of your PET/CT Scan

Unless you are on fluid restriction, please drink at least two glasses of plain water prior to your appointment.

Try to stay warm on the day of your scan.  If possible, do not wear clothing with belts, zippers, snaps or metal of any kind to your appointment.  Women should try to wear a bra without underwires or clips (sports bra).

If you have favorite music, please bring it with you to listen to while your scan is going on.

What to Expect the Day of Your PET/CT Scan

The technologist will escort you to the injection room and go over your detailed history.

Next the technologist will start an intravenous line and administer a radiopharmaceutical injection.

After the injection you will rest quietly in a reclining chair for 40 to 90 minutes.  Twenty minutes prior to the start of your scan you will be asked to empty your bladder.

Most PET/CT scans take between 20 minutes and 30 minutes.

After Your PET/CT Scan

For several hours following your scan, continue to hydrate to help the radiopharmaceutical pass out of your body.
