Positron Emission Tomography/Computed Tomography (PET/CT) is a state-of-the-art technology for diagnosing and evaluating cancers, coronary artery disease, and other pathologies. Scanners are becoming more common in hospital and outpatient settings, and technologists certified in both NM and CT are in demand.

Our PET/ Certificate Program prepares technologists to operate hybrid PET/CT scanners (which combine the concentrations of PET, which shows metabolism and function of cells, and CT, which shows detailed anatomy) and work independently in both PET and CT. PET/CT technologists produce highly accurate three-dimensional images that improve detection of cancer and show the exact location of it within the body.

This profession requires direct, noninvasive patient contact with healthy and critically ill inpatients and outpatients of all ages, injecting and positioning patients while on the table. Technicians work in a small, low-lit room, standing or sitting at a monitor while a patient is undergoing tests.

Why Jefferson PET/CT?

Our PET/CT Certificate Program, established in 2006, is the first formal PET/CT curriculum in the nation. This part-time, 12 month program is for certified nuclear medicine technologists, and is designed so that students can maintain their daytime jobs. Online didactic courses are completed during the Fall and Spring semesters. Clinical training is scheduled on a individual basis in the Fall, Spring and Summer.

After completing the didactic and clinical portions of the PET/CT Program, students may be eligible to take the certification exams offered by the American Registry of Radiologic Technologists® (ARRT) (CT) and/or the Nuclear Medicine Technology Certification Board (NMTCB) (CT and/or PET).

Technologists who are certified in both nuclear medicine and in computed tomography are highly employable, especially with PET specialization. Presently, employers are used to hiring technologists certified in only one of these areas.
