  2. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    The field strength of the magnet is measured in teslas – and while the majority of systems operate at 1.5 T, commercial systems are available between 0.2 and 7 T. 3T MRI systems, also called 3 Tesla MRIs, have stronger magnets than 1.5 systems and are considered better for images of organs and soft tissue.

  3. Physics of magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Physics_of_magnetic...

    Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...

  4. Superconducting magnet - Wikipedia

    en.wikipedia.org/wiki/Superconducting_magnet

    A magnetic resonance imaging (MRI) scanner using a superconducting magnet. The magnet is inside the doughnut-shaped housing and can create a 3-tesla field inside the central hole. Superconducting magnets have a number of advantages over resistive electromagnets.

  5. Diffusion-weighted magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Diffusion-weighted...

    Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.

  6. Radiofrequency coil - Wikipedia

    en.wikipedia.org/wiki/Radiofrequency_coil

    The reason for this is that the MRI is a poor radio transmitter and lacks an antenna. The RF frequency electromagnetic field produced in the "transmitting coil" is a magnetic near-field with very little associated changing electric field component (such as all conventional radio wave

  8. Magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance

    Magnetic resonance is a process by which a physical excitation is set up via magnetism. This process was used to develop magnetic resonance imaging (MRI) and nuclear magnetic resonance spectroscopy (NMRS) technology.
