Master the ARRT Nuclear Medicine Technology exam with confidence.
The ARRT Nuclear Medicine Technology credential certifies technologists who prepare and administer radiopharmaceuticals and operate imaging equipment to produce diagnostic studies and deliver therapeutic doses. Nuclear medicine technologists work with unsealed radioactive sources, gamma cameras, SPECT and SPECT/CT systems, and related instrumentation to evaluate organ function and structure. The credential is administered by the American Registry of Radiologic Technologists (ARRT).
It is important to note that the Nuclear Medicine Technology Certification Board (NMTCB) is a separate, related certifying board that also offers nuclear medicine credentials. Many technologists hold certification from ARRT, NMTCB, or both; employers and state licensing agencies may recognize either. This program focuses on the ARRT pathway, though much of the underlying knowledge overlaps.
The ARRT examination is a computer-based, multiple-choice test that assesses knowledge and cognitive skills across radiation safety, instrumentation and quality control, diagnostic and therapeutic procedures, radiopharmacy, and patient care. Candidates must satisfy education, ethics, and clinical competency requirements before sitting for the exam.
