NNC NSREN Specialist study guide
NNC NSREN Specialist · Work through your exam, one topic at a time.
The NNC NSREN Specialist credential is aimed at nuclear medicine technologists and radiopharmacy staff who prepare, assay, dispense, and administer radiopharmaceuticals, and who want formal recognition of that specialised skill set. Candidates typically already hold a nuclear medicine technology qualification and have hands-on exposure to a radiopharmacy or hot lab. The NNC NSREN Specialist study guide has 7 sections and about 2,266 words.
01Nuclear Medicine Instrumentation and Radiation Detection
Instrumentation questions test whether you can translate detector physics into image-quality decisions: which collimator, what energy window, why a flood is nonuniform, and how count rate affects a study. Expect calculation items on energy resolution, dead time, and collimator performance.
360 words, about 2 min02Radiation Safety, Dosimetry, and Regulatory Compliance
This domain tests ALARA reasoning, dose quantities and limits, external and internal dosimetry, and the regulatory rules that govern release, records, and shipping. Calculation items often use inverse-square, half-value layer, decay, and release criteria.
363 words, about 2 min03Radiopharmacy and Radiopharmaceutical Quality Control
Radiopharmacy items test generator operation, purity definitions, kit preparation, and release limits. You must distinguish radionuclidic, radiochemical, chemical, and biological purity, and calculate radiochemical purity from strip results.
316 words, about 2 min04Clinical Nuclear Medicine Imaging Procedures
Clinical procedure items test protocol selection, patient preparation, radiopharmaceutical choice, acquisition timing, and basic image interpretation across bone, cardiac, pulmonary, renal, thyroid, hepatobiliary, infection, and PET studies. Match the radiopharmaceutical to the physiology: Tc-99m MDP for bone, sestamibi or tetrofosmin for myocardial perfusion, MAA for lung perfusion, MAG3 or DTPA for renal function, I-123 or pertechnetate for thyroid, mebrofenin for hepatobiliary, FDG for glucose metabolism.
309 words, about 2 min05Therapeutic Nuclear Medicine and Patient Management
Therapy items test radionuclide selection, dose strategy, pre-treatment assessment, radiation safety instructions, release criteria, and follow-up for toxicity. Expect I-131, Lu-177 DOTATATE, Y-90 microspheres, Ra-223, and bone-pain palliation.
306 words, about 2 min06Quality Assurance, Quality Control, and Equipment Calibration
QA/QC items test the schedule, acceptance limits, and corrective action for gamma cameras, dose calibrators, survey meters, well counters, and ancillary equipment. You must know what is daily, weekly, quarterly, and annual.
307 words, about 2 min07Patient Care, Communication, and Professional Ethics
Patient-care items test communication, consent, identification, pregnancy and breastfeeding screening, extravasation management, privacy, and ethical handling of errors and incidental findings. The focus is behavior that protects patients and preserves trust.
