CNMT study guide
CNMT · Work through your exam, one topic at a time.
The CNMT credential is awarded by the Nuclear Medicine Technology Certification Board (NMTCB), an organization formed to create and maintain examinations for nuclear medicine technologists. According to the NMTCB, the credential is recognized in the nuclear medicine profession as the premier examination for nuclear medicine technologists, is recognized by state licensure agencies throughout the United States, and is recognized by employers as a valid, high-quality certification exam. The CNMT study guide has 5 sections and about 1,322 words.
01General Nuclear Medicine (CNMT)
The general CNMT domain tests the full arc of a study: radiopharmacy, instrumentation, patient preparation, imaging technique, and interpretation of common planar and SPECT exams. You must be fluent in decay modes, half-life math, radiopharmaceutical biodistribution, and the collimator/energy-window choices that make an image diagnostic.
288 words, about 1 min02Computed Tomography for Nuclear Medicine (NMTCB(CT))
This post-primary domain covers CT physics and operation as it applies to hybrid SPECT/CT and PET/CT. You need CT numbers (Hounsfield units), window width and level, reconstruction kernels, pitch, collimation, and dose metrics (CTDIvol, DLP).
290 words, about 1 min03Nuclear Cardiology Technology (NCT)
The NCT specialty centers on myocardial perfusion imaging, ventricular function, and the physics of cardiac SPECT and PET. Expect questions on Tc-99m sestamibi and tetrofosmin, thallium-201, stress agents, gating, and image processing.
248 words, about 1 min04Positron Emission Tomography (PET)
PET tests physics, radiopharmaceuticals, and clinical indications. F-18 FDG dominates oncology, but know F-18 NaF for bone, Ga-68 DOTATATE for neuroendocrine tumors, and amyloid and perfusion agents for brain.
251 words, about 1 min05Nuclear Medicine Advance Associate (NMAA)
The NMAA domain covers the advanced-practice support role: patient care, radiopharmacy handling, quality control, radiation safety, and assisting with therapeutic and diagnostic procedures under supervision. Expect questions on regulatory limits, contamination control, and documentation.
