Computed Tomography Exam Information
Section 1: Introduction
The NMTCB has developed a post-primary certification exam for computed tomography (CT). The NMTCB(CT) credential is designed to establish the competency of individuals who are qualified to perform in the role of a computed tomography technologist.
The NMTCB(CT) Examination has on-demand scheduling. Once an applicant's eligibility is confirmed, they will be able to schedule to sit for the exam at any time within three (3) months of the eligibility decision. The NMTCB(CT) exam will be administered nationally by IQT, Inc. Specific testing locations are available to view at IQT Testing Locations.
The examination consists of 200 multiple choice questions with three hours and 30 minutes to complete the exam. The application fee is $185.00.
The NMTCB(CT) certification must be renewed annually and certificants must maintain an active primary certification/registration in nuclear medicine, radiography, or radiation therapy in order to complete the yearly renewal of NMTCB(CT) certification. As an NMTCB(CT) certificant, you must complete a total of 12 hours of continuing education that are specific to Computed Tomography in each two year CE cycle. For individuals who hold a CNMT and a NMTCB(CT) credential, this requirement can count towards the CNMT continuing competence requirement of 24 total CE hours. The requirement for CNMT and NMTCB(CT) credentialed individuals includes a total of 24 CE hours, 12 of which must be specific to CT. If CT, PET/CT, or SPECT/CT is not specifically mentioned in the title of the CE activity, the certificant should retain the course description, objectives, or materials which demonstrate the activity is CT specific.
These instructions will familiarize you with the NMTCB's application and examination administration procedures. It is important that you understand and follow the procedures outlined in these instructions. Read them entirely and carefully before completing and submitting your application. You are responsible for knowing what is contained in these instructions. You will be more comfortable at the test site if you first familiarize yourself with the procedures and policies relating to the examination. Refer to these instructions for reference and contact the NMTCB office at the address at the bottom of this page if you have any questions. The NMTCB application and instructions are revised annually to reflect changes in policies and eligibility requirements. It is important that you complete and return the current application form.
The NMTCB does not discriminate against any individual on the basis of age, sex, race, religion, physical impairment, marital status, or national origin.
A total of 1,328 individuals are Active NMTCB(CT) Certificants.
Section 2: Eligibility Requirements
The eligibility requirements are as follows:
Section 3: Application Processing
Submitting Your Application
Read all instructions listed here carefully before completing the application form. Incomplete applications delay processing and may affect eligibility.
Applications may be submitted via the online NMTCB(CT) application page, with a Visa, MasterCard, or Discover payment for the examination processing fee of $185. The application fee is nonrefundable. Applications are processed in the order received. A request for withdrawal of an application received by the NMTCB office will result in total forfeiture of the exam application fee.
Acknowledgement of Application
Once the NMTCB has received your completed application and fees, an acknowledgement email will be sent to the email address provided on your application. Acknowledgement does not imply eligibility to sit for the examination. If you have not received this email within three weeks after you submitted the application, please contact the NMTCB office.
Name and Address Change
If you change your name or address after submitting your application, you must inform the NMTCB in writing immediately. If the NMTCB is not promptly notified, you may not receive your eligibility letter to take the examination, your official score report and certification card may be delayed and your certificate may be incorrectly prepared, resulting in a replacement cost. Your cooperation will ensure the most expeditious receipt of your NMTCB(CT) certificate.
Once the NMTCB has received a complete application, it is processed. All of your credentials must be verified or you may be determined ineligible to take the examination.
You will be notified by letter, telephone, or facsimile of any discrepancies between the information provided on your application and the information the NMTCB is able to verify. Any unresolved discrepancies may cause you to be determined ineligible to sit for the examination and result in postponement of your examination or permanent disqualification.
Once eligibility has been established, you will be emailed a username, password and instructions for scheduling your examination. This email will contain a link where you will login and schedule your appointment. Eligible candidates will have three (3) months in which to schedule an individual appointment and take the examination at one of the test sites. During the scheduling process, you will be provided with a list of test sites and available examination times. If you do not see an appointment available on your desired testing date and location, please call IQT at 1-866-773-1114 so that they may assist you in making those arrangements. Once you have scheduled your appointment, you will be able to print your candidate admission letter. Take your candidate admission letter and a currently valid government issued photo ID (driver's license, passport, etc.) to the test site when reporting for your appointment. Make sure to review the authorized materials list included in your candidate admission letter.
There may be delays in scheduling due to testing volume. It is to your advantage to schedule your appointment soon after receiving your authorization letter.
You will be notified in writing of any item(s) necessary to complete your file. All completed materials must be received by the NMTCB office in a timely manner or you will be determined ineligible. It is to your advantage to submit your application early in case clarification is required.
Applicants with a Disability
The NMTCB will make every reasonable effort to accommodate applicants for the Certification Examination who have a disability as that term is defined by the Americans with Disabilities Act of 1990. An applicant who wishes to request modifications in the environment because of a disability must notify the NMTCB in writing at the time of application and provide appropriate documentation about the disability and the needed modification. Upon receipt of a request for modifications in the testing environment, the NMTCB office will provide detailed guidelines concerning the required documentation to be submitted. The supporting documentation must be submitted in sufficient time to make proper arrangements to take the examination under conditions which will accurately reflect the applicant's achievement level. Requests for modifications will be considered on a case-by-case basis.
Replacement of Authorization Letter
If you lose your printed candidate admission letter you may reprint it by logging in to your account with the username and password that is provided in your confirmation email. Please note that the username and password are case sensitive.
Schedule/Reschedule/Cancellation of Examination
The NMTCB Specialty examinations are offered through IQT, Inc. A list of the testing centers and their locations is available to NMTCB candidates on the IQT website.
The NMTCB(CT) Specialty Examination is available on-demand. Once your application is approved, you may schedule yourself to sit for the exam at any time within three (3) months of the eligibility decision. Once you are determined eligible for the exam, you will be emailed instructions on how to schedule your examination day/time through IQT. You are expected to make an appointment and appear for the examination within the three (3) month testing period.
If you fail to show up for your examination at the scheduled time, do not have the proper identification, or do not have your admission document, you will not be allowed to sit for your exam. You will be considered a "No-Show", your examination fees will be forfeited, and you will be required to re-register and pay all fees prior to sitting for the exam. However, if an issue arises that prohibits you from making it to your scheduled exam, you may reschedule prior to (5) calendar days before your scheduled exam date by contacting IQT at 1-866-773-1114. You may be required to pay a rescheduling fee to process your request. If it is less than (5) calendar days, you will not be allowed to cancel or reschedule your exam unless one of the following 4 situations have occurred:
- Jury Duty
- Death in the immediate family
- Military Deployment
The immediate family is defined as a person's grandparents, parents, spouses, siblings and children.
If you experience any of the above, you MUST provide IQT with proper documentation before being rescheduled to a new date. Documentation must be submitted to IQT within 10 calendar days of your missed examination or it will not be considered for a reschedule. If none of the above are the reason for wanting to reschedule or cancel your exam less than 5 days prior to your exam date, then you will not be allowed to reschedule or cancel your exam.
If your area is experiencing inclement weather, it is your responsibility to contact your testing center to confirm if it is closed or delayed in opening. Most likely there will be a voice message on the testing center’s phone system to notify candidates of any change in business hours during the inclement weather. If you are unable to take your examination due to the inclement weather, you must contact IQT directly at 1-866-773-1114 or 1-727-733-1110 to reschedule your examination for a later date.
Candidates who fail to make an appointment during the eligibility period may extend the eligibility period by an additional three calendar months one time for a fee of $100.00 USD. This request must be submitted in writing to NMTCB. Candidates who fail to sit for the exam within one calendar year of eligibility approval will be required submit the full application fee in order to be reactivate the application and be considered eligible.
Checks returned by the bank to the NMTCB office for any reason are subject to a $45.00 returned check fee. The returned check fee and the replacement fee must be submitted in certified funds only (money order, cashier's check, etc.). A personal check cannot be accepted as replacement. All financial obligations to the NMTCB must be met before the eligibility letter is sent.
Reactivation of Application
Eligible candidates may repeat the examination by reactivating their eligibility by submitting a reactivation application online along with the current processing fee. A candidate may take the exam a maximum of two times within a 12 calendar month period. For re-examination, the eligibility criteria must still be met (current NMTCB, ARRT, or CAMRT nuclear medicine technology certification OR a current active CAMRT(RT), CAMRT(RTT), ARRT(R) or ARRT(T) certification). Applicants who were determined ineligible to take the examination, but who later meet the current eligibility requirements, may reapply, pay the current processing fee and reactivate their application. Applications are kept on file for three years from date of original application submission. After the three year expiration, candidates must meet current eligibility requirements at the time of new application. To reactivate an application you can visit the application page here.
When reactivating your eligibility, your request should include your current name, the name used on your original application (if changed), NMTCB(CT) file number, address and phone number, and date of last examination in your request.

Section 5: Privileges and Responsibilities
Passing the NMTCB(CT) Examination entitles you to certain privileges and obligates you to fulfill certain responsibilities. These are summarized below:
Privileges of Certification
CERTIFICATE: The most immediate benefit of certification is your certificate which will be mailed to you in approximately three (3) weeks after successful completion of the examination.
CREDENTIALS: Upon certification, you will also be granted the right to use the credential "NMTCB(CT)" after your name.
ANNUAL CERTIFICATION CARD: A personalized pocket-size annual certification card will be mailed to you after you receive your examination results. Most certificants carry the card with them. The certification card is a convenient method to provide your employer, governmental agencies and others with documentation that you are certified and registered in NMTCB(CT). An updated certification card will be mailed to you annually upon payment of the annual registration fees.
DIRECTORY LISTING: The names of all currently registered NMTCB(CT) technologists are listed in the "NMTCB Directory of Certified Nuclear Medicine Technologists", on the NMTCB website. The directory is made available only to other NMTCB certificants.
NMTCB NEWSLETTER: The NMTCB NEWS, published semi-annually, is provided to all certificants of nuclear medicine technology, CT, radiation safety, nuclear cardiology technology, PET, and NMAA. NMTCB NEWS covers topics of concern to certified technologists, trends in NMT education, developments in health care, nationwide salary comparisons, and other professional information.
Successful completion of the NMTCB(CT) post primary exam will be recognized by the NMTCB as the equivalent of 24 hours of CE.
Responsibilities of Certification
ANNUAL REGISTRATION: Perhaps the greatest responsibility of certification is annual registration. Once you are certified by the NMTCB, you remain certified and certification cannot be revoked without due process. It is necessary for you to register your certification annually with the NMTCB. Your annual registration fee pays for the privileges you enjoy as an NMTCB Certificant. More importantly, your annual registration fee supports the certification process for nuclear medicine professionals, thereby enhancing the profession of nuclear medicine technology.
Responsibilities of NMTCB(CT) certificants include maintaining an active primary certification/registration in nuclear medicine, radiography, or radiation therapy in order to complete the yearly renewal of your NMTCB(CT) certification. You will be allowed to renew your NMTCB(CT) certification only if you maintain active primary certification/registration.
As an NMTCB(CT) certificant, you must complete a total of 12 hours of continuing education that are specific to Computed Tomography in each two year CE cycle. For individuals who hold a CNMT and a NMTCB(CT) credential, this requirement can count towards the CNMT continuing competence requirement of 24 total CE hours. The requirement for CNMT and NMTCB(CT) credentialed individuals includes a total of 24 CE hours, 12 of which must be specific to CT. If CT, PET/CT, or SPECT/CT is not specifically mentioned in the title of the CE activity, the certificant should retain the course description, objectives, or materials which demonstrate the activity is CT specific. Read more about the CE policy.
Section 6: Appeals Procedure
Every effort is made to ensure that the NMTCB examination procedures are reasonable and that fair and equitable treatment is accorded to all applicants. To ensure fairness and a right of redress in the evaluation and processing of applications, examination procedures, and certification activities, the Directors of the NMTCB have established a formal appeals procedure which you must follow for appeal of any NMTCB policy, requirement, or decision.
If you are dissatisfied with or adversely affected by any action or decision of the administration of the NMTCB, you have the right to appeal such action or decision. If you wish to appeal any action or decision, your appeal must follow these guidelines.
