  2. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...

  3. Interventional magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Interventional_magnetic...

    Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...

  4. 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 ...

  5. MRI pulse sequence - Wikipedia

    en.wikipedia.org/wiki/MRI_pulse_sequence

    An MRI pulse sequence in magnetic resonance imaging (MRI) is a particular setting of pulse sequences and pulsed field gradients, resulting in a particular image appearance. [ 1 ] A multiparametric MRI is a combination of two or more sequences, and/or including other specialized MRI configurations such as spectroscopy .

  6. Reef knot - Wikipedia

    en.wikipedia.org/wiki/Reef_knot

    Photo of a tightened reef knot. The reef knot, or square knot, is an ancient and simple binding knot used to secure a rope or line around an object. It is sometimes also referred to as a Hercules knot or Heracles knot. The knot is formed by tying a left-handed overhand knot between two ends, instead of around one end, and then a right-handed ...

  7. Arthrogram - Wikipedia

    en.wikipedia.org/wiki/Arthrogram

    3-13k. An arthrogram is a series of images of a joint after injection of a contrast medium, usually done by fluoroscopy or MRI. The injection is normally done under a local anesthetic such as Novocain or lidocaine. The radiologist or radiographer performs the study using fluoroscopy or x-ray to guide the placement of the needle into the joint ...

  8. Hangman's knot - Wikipedia

    en.wikipedia.org/wiki/Hangman's_knot

    Surviving nooses in the United Kingdom show simple slipknots that were superseded in the late 19th century with a metal eye spliced into one end of the rope, the noose being formed by passing the other end through it. The classic hangman's knot was largely developed in the United States. Filmed hangings of war criminals in Europe after World ...

  9. Arthroscopy - Wikipedia

    en.wikipedia.org/wiki/Arthroscopy

    Arthroscopy is commonly used for treatment of diseases of the shoulder including subacromial impingement, acromioclavicular osteoarthritis, rotator cuff tears, frozen shoulder (adhesive capsulitis), chronic tendonitis, removal of loose bodies and partial tears of the long biceps tendon, SLAP lesions and shoulder instability. The most common ...
