ExploreAbout this exam
The American Board of Nuclear Medicine (ABNM) is a certifying board whose stated purpose is "Ensuring high-quality patient care by establishing standards in Nuclear Medicine." Initial certification is intended for physicians who have completed the training pathway ABNM recognizes and who wish to be examined and certified in nuclear medicine; the board separately administers continuing certification for diplomates who already hold its credential. The certification examination is a multiple-choice, computer-delivered test sampling the full breadth of the specialty. Content spans physics, instrumentation, and radiation safety; radiopharmaceuticals and radiochemistry; diagnostic planar and SPECT imaging; PET/CT and molecular imaging; and radionuclide therapy with clinical management. Items are built to probe applied clinical judgment rather than isolated recall, so expect image interpretation, protocol selection, dosimetry and safety reasoning, artifact recognition, and therapy decision-making. Preparation works best as a structured pass through each domain using a current nuclear medicine text, published procedure standards, and a dedicated physics review, followed by image-rich practice and timed mixed-domain question sets. Because eligibility rules, application deadlines, fees, scheduling, and pass standards are revised periodically and are published by ABNM itself (Initial Certification, Eligibility & Training, Schedule and Fees, Exam Resources), candidates should confirm every administrative detail directly with the board.

What you'll study
About ABNM Nuclear Medicine preparation
What is the format of the ABNM certification examination?
It is a multiple-choice examination delivered at a testing center. ABNM's site points candidates to a "Navigate the Exam" page, an exam calculator page, and an exam resources section, which are the authoritative places to confirm current mechanics. The retrieved ABNM pages do not publish an item count, section breakdown, or time limit, so verify those specifics with the board before you finalize a pacing plan.
What content areas does the exam cover?
Five broad areas: physics, instrumentation, and radiation safety; radiopharmaceuticals and radiochemistry; diagnostic planar and SPECT imaging; PET/CT and molecular imaging; and radionuclide therapy with clinical management. Treat this as a study map rather than an official blueprint. ABNM's own exam resources and study-guide pages are the only reliable source for current weighting and topic emphasis.
How difficult is the exam, and what score do I need to pass?
It is a specialty board examination aimed at physicians finishing supervised training, so it assumes working clinical fluency rather than introductory knowledge. The retrieved ABNM pages do not publish a passing standard, and any cut score you see quoted elsewhere may be outdated. Do not set a target percentage from memory; confirm the current standard through ABNM directly.
Can I retake the exam if I do not pass?
ABNM's public pages retrieved here do not state a retake policy, attempt limits, or waiting periods. Because these rules are administrative and can change between administrations, ask ABNM or consult the current application agreement and exam application materials before you assume a retake timeline. Planning as though you have one attempt is the safer study strategy.
How long does certification last, and what keeps it active?
ABNM operates a continuing certification program alongside initial certification, using the CertLink platform plus a continuing certification examination, with published policies on continuing certification, licensure, and professional conduct. Durations, deadlines, and participation requirements are set by the board and are not stated in the retrieved pages. Check the continuing certification section of the ABNM site for current requirements.
In what order should I study the five domains?
A practical sequence is physics and instrumentation first, because it underpins everything else; radiopharmaceuticals and radiochemistry second, since uptake mechanisms explain image findings; then planar and SPECT; then PET/CT and molecular imaging; and radionuclide therapy last, where dosimetry and safety reasoning draw on all four earlier areas. Finish with timed, mixed-domain sets so you practice switching topics under pressure.
What are the most common ways candidates lose points?
Three recurring patterns: weak quantitative reasoning in physics and dosimetry, so time is lost on calculation items; shallow protocol knowledge, where the correct study is chosen but the acquisition parameters or patient preparation are wrong; and underweighting therapy and safety questions. Another frequent problem is unrecognized artifact, which mimics disease. Practice distinguishing true findings from technical causes, and rehearse calculations until they are automatic.
How do I apply, and what does it cost?
Applications are submitted through ABNM, which publishes the certification exam application procedure and forms, an application agreement, eligibility and training requirements, and separate schedule and fees pages. The retrieved pages do not state a fee amount or deadline, and both change over time. Obtain the figures from ABNM's own schedule and fees page rather than from third-party summaries or older study material.
