How to Become a CT Tech & Advance Your Career
Diverse, fascinating, and essential, the rapidly growing field of radiology offers exciting opportunities for ambitious professionals. Among the many available niches is a path that may seem familiar but is not well-understood outside of the healthcare sector: computed tomography.
This imaging technique is crucial for providing insight into internal anatomy. It plays a central role in diagnosing and understanding many conditions. Successful scans would not be possible, however, without the hard work of specialized radiologic technologists.
Keep reading to learn why this imaging modality is so important and how dedicated CT technologists make a difference for patients and clinical employees alike.
What Is a CT Technologist?
A computed tomography (CT) technologist is a specialized practitioner responsible for producing cross-sectional images. These, along with in-depth feedback from the technologist, help radiologists diagnose a variety of diseases and acute conditions.
MTMI's Mark Bake, DBA, MS, BS, RT(R)(CT) explains that this role is defined, in part, by the technologist's background and how they handle imaging. "A CT technologist generally has a radiology background and obtains special cross-sectional imaging to help providers diagnose a patient."
CT techs usually work in a hospital, a provider’s office, or a freestanding imaging center.
What Does a CT Tech Do?
CT techs are responsible for operating assigned scanning equipment to perform the radiologic exams. This produces diagnostic images of the patient's anatomy, which can then be sent to radiologists for analysis. Should any issues involving the equipment or technology arise, CT techs should document and report these concerns promptly.
According to Bake, one of the main distinctions between the CT tech's role and that of other radiology professionals involves the sheer quantity of images produced. He explains that, instead of relying on just one or two images, CT techs "take hundreds of images in a very short time period." Technologists may also be asked to work closely with radiologists to guide drainages or biopsies.
There's more to CT scanning than simply operating equipment. These empathetic professionals interact closely with patients and can provide a much-needed source of comfort during a difficult or overwhelming time.
CT techs should maintain a patient-centered approach, complete with detailed and helpful instructions, plus empathetic responses as patients ask questions or cite concerns. This is particularly important while utilizing IV contrast, as patients may need to hold still for what, to them, feels like a substantial amount of time.
What Is Computed Tomography?
The everyday work of a CT tech is difficult to understand without recognizing the inherent complexity and value of computed tomography, a non-invasive diagnostic procedure. This cross-sectional imaging technique involves a series of X-rays, which are taken from many angles to produce detailed images of the soft tissues, blood vessels, and bones.
Computed tomography (CT) is often confused with other imaging solutions. Technologists must be thoroughly familiar with all imaging approaches, as they will occasionally come across situations in which they're asked to perform CT scans but ultimately realize that other imaging techniques are preferable. Our breakdown of common terms and abbreviations should help you understand where and when CT scans come into play.
CAT Scan vs. CT Scan
Many patients are surprised to discover that the terms CAT scan and CT scan reference the same type of diagnostic procedure. Short for "computed axial tomography," CAT was widely used for years but has since been largely replaced by the simpler term "computed tomography."
Given the increased versatility of today's machines, the previous terminology is not always entirely accurate. Today's machines utilize sagittal or coronal planes in addition to the axial images for which they were originally known. The ‘A’ in CAT scan was therefore dropped from the acronym, changing it to CT.
PET/CT vs. SPECT/CT
Positron emission tomography (PET) relies on tracers to provide insight into metabolic activity. These tests may be completed along with CT scans or even built into a single scanner known as the PET/CT.
Single photon emission computed tomography (SPECT) involves a lower-cost alternative that replaces positron-emitting radioisotopes with gamma-emitting radioisotopes. This produces less contrast but remains a valuable option for analyzing a variety of organs and tissues.
Both PET and SPECT make it possible to blend aspects of nuclear medicine with CT. This is especially valuable when diagnosing or staging cancer, as the combination of these modalities can reveal hotspots indicating whether (or to what extent) cancer has spread.
CT vs. MRI vs. X-Ray
CT scans are often confused with MRI scans and X-rays. All share the basic purpose of assisting with diagnostics, but there are many considerable differences worth addressing.
CT scans produce remarkably high levels of detail and are frequently relied upon in emergencies and trauma. These scans may reveal pathologies such as blood clots and can often pinpoint subtle fractures that are difficult to spot via X-rays. Still, X-rays have their place: in first-line imaging, especially when expedited results are required.
Meanwhile, MRIs avoid radiation altogether and are therefore distinct from both X-rays and CT scans. Although they can be valuable in many contexts, MRIs are most commonly used to gather information on various musculoskeletal conditions. MRI technologists require their own specialized training to learn this unique imaging technique.
How to Become a CT Technologist
With so many types of scans available for modern diagnostics, there is an increased need for niche skills, including the ability to operate and understand highly complicated equipment. Among these many opportunities, CT technology is especially compelling, given the prevalence of CT scans within urgent care.
The path to becoming a CT technologist is similarly diverse. In general, any aspiring radiologic technologist can expect to follow a few basic steps: get the right degree and certification followed by a state license, if required. We delve into each step in detail below:
1. Degree in Radiology
An associate degree is a must for any radiologic technologist, but it is especially important for anyone who wants to eventually work in computed tomography. The right degree will provide a strong foundation in anatomy, physiology, and medical terminology while also helping aspiring technologists develop stronger communication and collaborative skills. Radiology remains the main method for getting into CT—and CT is often purposefully built into the curriculum.
2. ARRT Certification
Following graduation, take steps to get certified with the American Registry of Radiologic Technologists ® (ARRT ®). Offering credentials in a variety of disciplines, ARRT is the industry's go-to resource for everything from magnetic resonance imaging to nuclear medicine technology.
Certification in computer tomography is available, but you will need to meet a variety of clinical experience and structured education requirements to qualify. CT represents a post-primary form of certification, so it must be preceded by ARRT credentials in supporting disciplines.
3. State Licensure (If Necessary)
State requirements can vary significantly, so take a close look at rules and regulations in your region to determine whether you need to take any additional steps to get licensed after you secure your degree and ARRT certification. When in doubt, look to the American Society of Radiologic Technologists (ASRT) for insight into state-by-state licensure.
