Get a Clear Picture of Your Future with a CT Technologist Certificate
The computed tomography (CT) certificate of specialization (CS) at St. Louis Community College prepares imaging professionals to earn CT credentials and take the next step in their medical imaging careers. This program is designed for radiographers, nuclear medicine technologists and radiation therapists who want specialized CT training. Students develop practical skills in cross-sectional anatomy, CT physics and instrumentation, radiation safety and patient care in imaging.
You can complete the program in just two semesters, or less than one year, giving you a clear and focused path to certification. Graduates are eligible to take the post-primary CT registry examination through the American Registry of Radiologic Technologists (ARRT).
What is Computed Tomography at St. Louis Community College?
Computed tomography is a medical imaging technology that uses X-rays to produce detailed, cross-sectional images of the body. These images help physicians detect, diagnose and monitor conditions in the brain, spine, chest, abdomen, pelvis and limbs.
STLCC’s CT imaging program teaches students how to operate CT scanners, follow safety protocols, optimize image quality and provide excellent patient care.
Students complete CT clinical rotations at hospitals and imaging centers across St. Louis, gaining real-world experience in performing diagnostic procedures, patient positioning and image evaluation. Students who already perform CT in their current roles can apply prior experience to meet program requirements. Practice with hybrid imaging equipment and instruction in diagnostic imaging procedures ensures graduates are fully prepared for registry exams and clinical work.

What Can You Do with a CT Certificate?
With a computed tomography certificate, graduates can work as registered CT technologists, operating CT and hybrid imaging equipment, performing diagnostic imaging procedures and providing essential information that supports patient care decisions. Technologists work with patients of all ages and collaborate with health care teams in hospitals, outpatient imaging centers and other medical facilities.
The program also prepares students for continued growth, including advanced imaging certification or additional health care education. Many graduates use the certificate as a foundation to:
- Expand their skills in CT and other imaging modalities
- Pursue leadership or advanced clinical roles
- Take on specialized certifications in advanced imaging
- Explore career opportunities in health care imaging training across St. Louis
