However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body’s structures.ĬT scans are fast and detailed. Torn or detached ligaments, tendons, muscles and cartilage, such as:Ī CT scan, or computed tomography scan, sends radiation through the body.MRIs are especially useful for spotting sports injuries and musculoskeletal conditions, including: An MRI offers excellent contrast resolution for bones and soft tissues.” “Often, problems are too subtle to see on an X-ray,” says Fayad. An MRI scanner is a highly specialized machine and may not be available in some imaging facilities or emergency rooms at other hospitals. Unlike X-rays and CT scans, MRIs don’t use any radiation.Īt Johns Hopkins, we’ve developed very fast, high-resolution MRIs that can be done in 10 minutes or less. Protons in the body react to the energy and create highly detailed pictures of the body’s structures, including soft tissues, nerves and blood vessels. What injuries require an MRI?Īn MRI, or magnetic resonance imaging, uses a powerful magnet to pass radio waves through the body. However, even if your doctor suspects a soft tissue injury like a tendon tear, an X-ray might be ordered to rule out a fracture. “That’s usually the first-line imaging,” explains Laura Fayad, M.D., M.S., chief of musculoskeletal imaging at Johns Hopkins Medicine “X-rays often allow us to see major problems with the bones.”Īn X-ray won’t show subtle bone injuries, soft tissue injuries or inflammation. An X-ray exam only takes a few minutes to complete. They appear gray or black on the image.Īn X-ray is the fastest and most accessible form of imaging. Soft tissues allow the radiation to pass through. Areas with high levels of calcium (bones and teeth) block the radiation, causing them to appear white on the image. Resolution (level of detail in the images)Īn X-ray, also called a radiograph, sends radiation through the body.These imaging technologies differ widely when it comes to: They create images using various forms of electromagnetic energy such as radio waves and X-rays. Learn the differences between a CT scan, MRI and X-ray so you can have an informed discussion with your doctor about which type of imaging is right for you.ĬT scans, MRIs and X-rays are all diagnostic tools that allow doctors to see the internal structures of the body. However, imaging tests are not the same as one another. ![]() Imaging tests are extremely powerful tools that can help doctors diagnose a range of conditions. If you’ve ever had an injury, chances are you’ve had an imaging exam. ![]()
