Guide to Diagnostic Imaging Careers

The medical field is quite vast and it doesn’t take years of medical or nursing school to find a rewarding career helping sick people. Diagnostic imaging has been around in one form or another for more than a century. However, the ways in which we are able to look inside the human body to diagnose all types of ailments have only become more numerous since then. To pursue any type of diagnostic imaging career does require a bit of training as well as hands on patient experience, but it’s a job where you can truly make a difference, working closely with both patients and physicians to diagnose illnesses and develop treatment plans.

Following is a rundown of the various types of diagnostic imaging careers that are available in the medical field as well as a collection of useful links that can help you to determine whether diagnostic imaging is the right career choice for you.

The Diagnostic Medical Sonographer Career

While you may imagine diagnostic medical sonographers as doing little more than examining expectant mothers, the truth is that ultrasound technology is useful for many different medical applications. Diagnostic medical sonographers, also known as ultrasound technicians, use ultrasound machines to create images of patients’ internal organs and tissues. They may specialize in a certain part of the body, such as abdominal sonographers or breast sonographers, or in a certain field, such as obstetric and gynecologic sonographers. Some general responsibilities include:

  • preparing patients for the ultrasound procedure

  • maintaining ultrasound equipment

  • interpreting images with physicians

  • keeping detailed patient records

According to the BLS, diagnostic medical sonographers are expected to be in extremely high demand through at least 2022, with the field adding 27,000 new jobs in the U.S. over that time at an increase of 45% (BLS, 2013). The median annual wage in the field is $65,860, with the lowest paid 10% earning less than $44,900 and the highest paid 10% earning more than $91,070.

Diagnostic medical sonographers may earn an associate’s degree or a bachelor’s degree in the field, but some also go through non-degree certification programs. In most cases, graduates will then need to become certified by the American Registry for Diagnostic Medical Sonography (ARDMS) or the ARRT before seeking employment. Some employers will hire new graduates provided they become certified within a specific amount of time.

The Radiologic Technologist Career

A radiologic technologist is trained in some of the most prevalent imaging technology, namely x-ray machines. This career involves using these machines on patients as well as maintaining them to ensure they stay in good working order over time. Other responsibilities that radiologic technologists may have include:

  • following physician orders

  • protecting areas not to be imaged from radiation

  • taking patient history

  • physically moving and adjusting patient for proper imagine

  • keeping detailed records

According to the Bureau of Labor Statistics (BLS), radiologic technologists are in high demand. In 2012, 199,200 were employed in the U.S. while by 2022 there are expected to be 240,800 (BLS, 2012). That represents an increase of 21%, which is faster than the average for all jobs in the country. Although specific salaries are always dependent on a number of factors, the median salary for a radiologic technologist in the U.S. is $54,620 per year. 10% earned less than $37,060 while the top 10% earned more than $77,160.

In order to qualify for a position in radiologic technology, an associate’s degree is the minimum required education, although there are also postsecondary training that least to certificates, and bachelor’s degree. There are many community colleges that offer training programs in radiologic technology. The right program for any individual in training will depend on what type of job they hope to find as well as how much time and tuition they are willing to invest. Prospective radiologic technologists should look for training programs that have been accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT). Many positions require that radiologic technologists be certified by the American Registry of Radiologic Technologists though some states have their own separate licensing requirements as well.

The MRI Technologist Career

For those who may already be radiologic technologists but who are looking to further their careers in the field of diagnostic imaging, MRI technologist may be a good path. These professionals work with Magnetic Resonance Imaging machines to take more detailed images of patients than are available through x-ray alone. On a daily basis, MRI technologists may be expected to:

  • administer contrast dye to patients

  • properly position the MRI machine

  • ensure proper maintenance for the MRI machine

  • use judgement in positioning machine and patient

  • adhere to hygienic standards

  • have a thorough knowledge of human anatomy and physiology

Most MRI technologists are certified as radiologic technologists first, and then gain professional experience working with MRI machines before earning that certification. However, there are specific training programs geared solely towards MRI technologists.

MRI technologists have more experience and are more specialized than radiologic technologists. Therefore, there are fewer of them and demand is high. According to the BLS, demand for MRI technologists is expected to increase by 24% from 2012 to 2022, with 37,200 more jobs becoming available over that time (BLS, 2012). Salaries are also higher, with the median annual salary for MRI technologists being $65,360, the lower 10% being $46,400, and the upper 10% earning more than $89,130.

Like radiologic technologists, MRI technologists are are certified by the ARRT. Applicants for certification who are not already certified in another area by the ARRT must have completed an academic degree in MRI technology at an accredited institution, such as an associate’s or bachelor’s degree, before sitting for the certification exam. Those who are already certified as radiologic technologists, nuclear medicine technologists, radiation therapists, or sonographers, do not need to need the academic degree requirement.

The Nuclear Medicine Technologist Career

A career in nuclear medicine technology is a highly specialized area of diagnostic imaging. While a nuclear medicine technologist still focuses on taking images of internal organs and systems, they are also responsible for administering radioactive drugs that help possible trouble areas show up on the images they take. Nuclear medicine technologists then work closely with physicians and other specialists to interpret the images they take. Other typical responsibilities of a nuclear medicine technologist include:

  • counseling patients on imagine procedures

  • protecting themselves and patients from unnecessary exposure to the chemicals with which they work

  • scanner maintenance

  • patient monitoring

Like other diagnostic imaging careers, the outlook for nuclear medicine technologists is quite good. According to the BLS 4,200 nuclear medicine jobs are expected to be added between 2012 and 2022, which represents an increase of 20% (BLS, 2012). Pay for nuclear medicine technologists is also quite competitive among other diagnostic imaging careers with the median wage being $70,180 per year. The lowest paid 10% earn less than $50,560 while the highest paid 10% earn more than $93,320. THis is significantly higher than the overall average salary of $34,750 as well as the median pay for all health technologists and technicians, which is $40,380.

There are a number of educational pathways that prospective nuclear medicine technologists can take. Some are able to find employment with only an associate’s degree in nuclear medical technology, but many go so far as to earn a bachelor’s degree from a college or university. There are also hospitals that offer certification programs for those individuals who have already completed an educational program in radiology.

Some states require that nuclear medicine technologists be licensed within the state while others accept national certification and still others do not require any specific certification. Certification is available from the ARRT or the Nuclear Medicine Technology Certification Board (NMTCB).

The Computed Tomography Technologist Career

Although some programs teach computed tomography (CT) technology alongside MRI technology, despite their similarities, in many hospitals they are two separate functions and two separate jobs. CT technologists use CT machines to examine the body using a machine that emits radiation. CT scanning machines are more appropriate for identifying and imagine bone injuries as well as lunch and chest issues and certain cancers. MRI machines, on the other hand, are more appropriate for soft tissue damage, spinal cord injuries, and brain injuries, especially tumors.

The responsibilities of a CT technologist are similar to that of an MRI technologist, only with their specific type of machinery and include:

  • patient transfer and safety

  • machine maintenance, including changing any necessary settings

  • emergency scans

  • interfacing with physicians

The BLS does not maintain separate statistics for CT technologists, but we are able to extrapolate from the data for radiologic technologists that demand for this particular career is expected to grow over the next decade.

CT technologists can earn national computed tomography certification from the ARRT. Applicants must have prior standing with the ARRT in either radiography or nuclear medicine technology before pursuing their CT certification.
