MRI Technologists: The Importance of Ergonomics in their Work Environment

How Outdated MR Coils, Repetitive Motions, and Patient Positioning Contribute to Injuries

An MRI technologist helps play a critical role in diagnosing and treating patients. However, the nature of the work can strain their bodies significantly, leading to injuries that can impact their ability to perform their job. Studies have shown that MRI technologists face a substantially higher risk of musculoskeletal disorders than the general population due to poor ergonomic conditions in their work environment.*

The use of outdated MR coils, repetitive motions, and positioning of patients are among the main factors contributing to these injuries. In this article, we will explore the importance of ergonomics in the work environment of MRI technologists and how addressing these factors can help prevent injuries.

Why is Ergonomics Important for MRI Technologists?

Ergonomics is the science of designing a workplace to fit the worker, considering their capabilities and limitations. For MRI technologists, a poorly designed workplace can lead to repetitive stress injuries, musculoskeletal disorders, and other health problems that can impact their ability to work effectively. By developing a workplace that considers the worker's needs, it is possible to reduce the risk of these injuries and improve job performance.

Outdated MR Coils

MR coils are an essential component of MRI scanners and are one of the critical tools an MR technologist uses. Outdated MR coils are a significant concern for MRI technologists. The design and construction of MR coils have advanced considerably over the past few years, resulting in more ergonomic designs using 3D-printed technology. However, many MRI machines still use outdated MR coils that are heavy, bulky, and difficult to maneuver and position. For example, a traditional MR body coil can weigh over 5 lbs versus a 3D-printed one weighing less than one pound. The constant maneuvering of heavy MR coils can lead to musculoskeletal disorders (MSDs), particularly in the shoulder and back, due to the repetition of movement, which affects the muscles, tendons, nerves, and joints. According to the Bureau of Labor Statistics, MSDs account for 33% of all worker injury and illness cases that require time away from work. Statistics show that 47% of MRI technologists experience pain or discomfort in their shoulder or neck, with 23% reporting low back pain. In a survey of 329 MRI technologists, 92% said that they had experienced some form of musculoskeletal pain during their careers, with 68% reporting that the pain had affected their job performance.

Using outdated MR coils is one of many factors contributing to these injuries. The repetitive motions required to position the coils correctly and the positioning of the patient can also put a significant strain on the body.

Repetitive Motions

Part of the role of MRI technologists is to physically and repeatedly position MR coils precisely to obtain high-resolution images. This often requires repetitive motions, such as reaching, lifting, and twisting. In MRI, technologists are required to move patients in and out of the MRI scanner, adjust the MR coils, and operate the equipment. These tasks cause repetitive shoulder, arm, wrist, and hand motions. Over time, these repetitive motions can cause musculoskeletal disorders, such as tendonitis, carpal tunnel syndrome, and rotator cuff injuries. According to the Occupational Safety and Health Administration (OSHA), repetitive motions are a leading cause of MSDs. In a survey by the American Society of Radiologic Technologists (ASRT), 82% of MRI technologists reported that they perform repetitive motions that cause discomfort or pain. Of those, 45% said that the pain affected their job performance.

Patient Positioning

Patient positioning is a critical part of the MRI process. MRI technologists must ensure the patient is positioned correctly to obtain high-resolution images. Positioning often requires physical force to lift and move the patient into the correct position. This can put a significant strain on the body, especially if the patient is obese, elderly, or poor posture is used by the technologist. Constant patient repositioning can cause MSDs such as back pain, herniated disks, and muscle strains. According to the Centers for Disease Control and Prevention (CDC), musculoskeletal disorders are healthcare workers' most common type of work-related injury, and an ASRT survey states that 68% of MRI technologists reported that they experience pain or discomfort in their back or shoulder due to patient positioning. Of those, 19% said that the pain affected their job performance.

Tips to Improve Ergonomics

Here are some ergonomics tips for MRI technicians to reduce the risk of injury and promote good posture:

1. Use adjustable workstations and chairs that can be customized to fit your body size and shape.
2. Use anti-fatigue mats in areas where you stand for prolonged periods to reduce strain on your feet, legs, and lower back.
3. Use proper lifting techniques when handling heavy equipment or patients. Bend at the knees, keep your back straight, and use your leg muscles to lift rather than your back.
4. Avoid awkward postures and repetitive motions, such as twisting or bending at the waist, reaching above shoulder height, or holding your arms out for extended periods.
5. Use proper hand positioning when operating equipment to reduce strain on your wrists and fingers.
6. Take frequent breaks and stretch your muscles to relieve tension and prevent fatigue.
7. Maintain good lighting in your work area to reduce eye strain and promote good posture.
8. Use a footrest to reduce pressure on your lower back and legs when sitting for long periods.
9. Keep your work area organized and clutter-free to reduce the risk of tripping or falling.
10. 10. Use proper communication and teamwork when working with patients to reduce the need for excessive physical exertion.

The importance of ergonomics in the work environment of MRI Technologists cannot be overstated to optimize the interaction between people, technology, and the work environment to maximize productivity, safety, and comfort. Ergonomic interventions such as replacing legacy MR coils, using adjustable equipment, providing patient positioning aids, and educating patients on how to position themselves correctly can help to reduce the risk of injuries. By prioritizing ergonomics, healthcare organizations can improve the well-being of MRI Technologists and enhance the quality of care for patients.
