PET/CT Imaging

PET (Positron Emission Tomography) and CT (Computed Tomography) are both standard imaging tools physicians use to pinpoint disease states in the body. Reading Hospital uses a Philips GEMINI TF (TruFlight) system PET/CT scanner to offer the next dimension in diagnostic imaging power.

How PET/CT Imaging Works

PET/CT is a powerful imaging technique that provides diagnostic and anatomic information about the human body in a single scan. This allows your physician to examine your entire body at once, making it easier for your doctor to diagnose problems, determine the extent of disease, prescribe treatment, and track progress.


Appointments are offered five days a week and require a physician referral. Your appointment for your PET/CT should be scheduled by your physician’s office.

A 24-hour cancellation notice is required because the medicine used for the scan is specially ordered for you. If you need to reschedule or cancel your appointment, contact Central Scheduling at 484-628-8611.

For any questions regarding the PET/CT procedure, contact the Nuclear Medicine Department at 484-628-8401 Monday through Friday from 7 a.m. to 3:30 p.m.
