CT can be an exciting and fulfilling career. As a CT technologist, you’ll likely work in a hospital or an imaging center. You’ll perform scans on all parts of the body for a variety of reasons. Some patients need imaging to diagnose a disease or an acute condition. Others need CT scans in emergencies, so physicians can understand the extent of injuries. While you perform the procedures, your skills and confidence will be critical as you balance image quality with radiation dose. You’ll also help inform and calm nervous patients. 


To earn postprimary credentials in CT, you must maintain compliance with the ARRT Standards of Ethics and fulfill additional requirements in structured education, clinical experience, and examination. You must also meet a supporting discipline prerequisite. For CT, you must first be certified and registered in Radiography, Nuclear Medicine Technology, or Radiation Therapy. Your Nuclear Medicine Technology credentials may be through ARRT or the Nuclear Medicine Technology Certification Board (NMTCB). 

To get started, review these important CT documents:

  • Postprimary Eligibility Pathway Handbook
  • Structured Education Requirements—through June 30, 2022
