  2. 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 ...

  3. 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.

  4. Fast low angle shot magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Fast_low_angle_shot...

    In 2010, an extended FLASH method with highly undersampled radial data encoding and iterative image reconstruction achieved real-time MRI with a temporal resolution of 20 milliseconds (1/50th of a second). [4] [5] Taken together, this latest development corresponds to an acceleration by a factor of 10,000 compared to the MRI situation before ...

    However, greater capital costs and effects of off-resonance artefact on image quality mean that many studies are routinely performed at 1.5T. [29] Imaging at 7T field strength is a growing area of research, but is not widely available. [30] Current manufacturers of cardiac-capable MRI scanners include Philips, Siemens, Hitachi, Toshiba, GE.

  6. Relaxation (NMR) - Wikipedia

    en.wikipedia.org/wiki/Relaxation_(NMR)

    The fact that T 1 relaxation involves an interaction with the surroundings is the origin of the alternative description, spin-lattice relaxation. Note that the rates of T 1 relaxation (i.e., 1/T 1) are generally strongly dependent on the NMR frequency and so vary considerably with magnetic field strength B. Small amounts of paramagnetic ...

    All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
