Here are all the possible meanings and translations of the word magnetic resonance imaging.

Princeton's WordNet

  1. magnetic resonance imaging, MRI(noun)

    the use of nuclear magnetic resonance of protons to produce proton density images


  1. magnetic resonance imaging(n.)

    a medical diagnostic procedure utilizing the phenomenon of nuclear magnetic resonance to generate images of internal parts of the body. It depends on the differential absorption of electromagnetic radiation by different types of living tissue in a magnetic field. It is complementary to X-ray imaging in that the softer tissue show more prominently in magnetic resonance images, rather than bone, as with X-rays. It is a non-invasive procedure, allowing such images to be obtained without penetration of the tissue by objects. It is abbreviated MRI. As with computerized tomography, the results are usually presented as images of sequential planar sections of that part of the body of concern to the physician.


  1. magnetic resonance imaging(Noun)

    A technique that uses nuclear magnetic resonance to form cross sectional images of the human body for diagnostic purposes.


  1. Magnetic resonance imaging

    Magnetic resonance imaging, nuclear magnetic resonance imaging, or magnetic resonance tomography is a medical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance to image nuclei of atoms inside the body. MRI can create more detailed images of the human body than possible with X-rays. An MRI scanner is a device in which the patient lies within a large, powerful magnet where the magnetic field is used to align the magnetization of some atomic nuclei in the body, and radio frequency magnetic fields are applied to systematically alter the alignment of this magnetization. This causes the nuclei to produce a rotating magnetic field detectable by the scanner—and this information is recorded to construct an image of the scanned area of the body. Magnetic field gradients cause nuclei at different locations to precess at different speeds, which allows spatial information to be recovered using Fourier analysis of the measured signal. By using gradients in different directions, 2D images or 3D volumes can be obtained in any arbitrary orientation. MRI provides good contrast between the different soft tissues of the body, which makes it especially useful in imaging the brain, muscles, the heart, and cancers compared with other medical imaging techniques such as computed tomography or X-rays. Unlike CT scans or traditional X-rays, MRI does not use ionizing radiation.

U.S. National Library of Medicine

  1. Magnetic Resonance Imaging

    Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

Sample Sentences & Example Usage

  1. Manuela Ferreira:

    Adults with sudden back pain do not need to rush to get an X-ray or magnetic resonance imaging (MRI), unless the clinician suspects the patient has a more serious condition, such as fracture or cancer, less than 5 percent of patients with low back pain, however, will fall into this category.

  2. James Brown:

    The economy is changing with an emphasis on technology skills across all sectors. The emphasis now is that not all STEM jobs require four-year degrees. When I was growing up, you had what were called ‘blue collar jobs,’ now you have technicians who need to be highly skilled in tech. You need people who can repair MRI (magnetic resonance imaging) machines, or work on electric cars, you now need technicians who need to have really hard STEM skills. That’s a skill set that will be growing over the next five years, it will be more in demand, and giving students the foundation for those kinds of careers starts in school.
