- After receiving a referral and scheduling your appointment, your exam will be performed at the Tully Health Center and takes about an hour.

What Is A PET/CT Scan?
This two-in-one exam gives a highly detailed image and functional information of a specific body area. The PET scan highlights the abnormal metabolic function of cancer cells, while the CT portion depicts the size and location of the tumor within the body. Together, these images create 3D pictures that enable doctors to make more informed decisions regarding your cancer treatment.What You Should Know About Your PET/CT Scan
