Essential Information

A Bachelor of Science in Radiologic Technology program trains candidates to create various types of diagnostic images, examine the results and administer radiation therapy. Students learn to use the latest technology and techniques for diagnostic medical evaluation, and about procedures and safety precautions. Hands-on practice is received during clinical training at a healthcare facility. Some CAT scan technology programs require applicants to be registered radiologic technicians, while others simply mandate that they have completed basic radiology coursework. Previous field work may also be required. This degree takes 4 years to complete.

After receiving a bachelor's degree and passing the American Registry of Radiologic Technologists (ARRT) exam, students must complete a year of clinical practice to qualify for the CT certification exam. Graduates with these credentials are employed in hospitals, clinics and other health care related locations.

Bachelor's Degree in CAT Scan Technology

Students in a bachelor's degree program in radiography take general education courses, along with science classes focused on radiology and corresponding technology. Most schools provide students with academic training during the first two years. Some topics covered in radiologic technology programs are:

  • Structure and function of the body
  • Medical terms and procedures
  • Healthcare ethics
  • Radiographic technology and procedures
  • Radiation protection
  • Patient psychology

Employment Outlook and Salary Info

According to the U.S. Bureau of Labor Statistics (BLS), job opportunities for radiologic technologists are expected to grow by 9% from 2018-2028 (

Hospitals may be the primary employers of radiologists currently, but the increasing need for diagnostic imaging and the availability of the technology will create more jobs in clinics and diagnostic centers. According to the BLS, radiologic technologists with certifications in multiple imaging types, like CT scan, magnetic resonance imaging (MRI) and mammography, were predicted to be in higher demand.

In 2018, the BLS reported that salaries for radiologic technologists ranged from $40,630 to $86,350. The median salary was $59,520.

Continuing Education Information

Most educational advancements can be achieved by working with a physician in a specialized area of radiologic technology, such as computed tomography, mammography, MRI or biological dosimetry. Some schools offer classes to help students qualify for certification in these areas. A master's degree in the field is also available for professional radiologists. The degree requires two years of study in radiological technology and field research.

CT Scan Certification

Students who wish to perform CAT scans are required to pass the American Registry of Radiologic Technologists' (ARRT) computerized tomography (CT) certification exam. Some schools offer sufficient CT training in their radiologic technology degree programs, while students in other programs may need to take a certification course.

Preparation for CT certification may require between one semester and a year of coursework. To be eligible for a CT certification course, enrollees must hold ARRT radiologic technologist certification and pass a medical examination. In a CT certification program, students learn ethics and procedures as well as the latest imaging technology and diagnostic techniques. Many programs also offer physician supervised practice in a clinical setting.

Students in a Bachelor of Science in Radiologic Technology program will have an opportunity to advance their understanding of relevant concepts, such as healthcare ethics, anatomy, current technology and procedure.
