  2. Magnetic resonance angiography - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_angiography

    Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.

  3. Arthrogram - Wikipedia

    en.wikipedia.org/wiki/Arthrogram

    Shoulder arthrography can be used to study tears of the rotator cuff, glenoid labrum and biceps. [2] The type of contrast injected into the joint depends on the subsequent imaging that is planned. For pneumoarthrography, gas is used, for CT or radiographs, a water-soluble radiopaque contrast, and for MRI, gadolinium .

  4. Arteriovenous malformation - Wikipedia

    en.wikipedia.org/wiki/Arteriovenous_malformation

    ct, mri, mra An arteriovenous malformation ( AVM ) is an abnormal connection between arteries and veins , bypassing the capillary system. Usually congenital , this vascular anomaly is widely known because of its occurrence in the central nervous system (usually as a cerebral AVM ), but can appear anywhere in the body.

  5. Physics of magnetic resonance imaging - Wikipedia

    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 ...

  6. Steady-state free precession imaging - Wikipedia

    en.wikipedia.org/wiki/Steady-state_free...

    Steady-state free precession (SSFP) imaging is a magnetic resonance imaging (MRI) sequence which uses steady states of magnetizations. In general, SSFP MRI sequences are based on a (low flip angle) gradient echo MRI sequence with a short repetition time which in its generic form has been described as the FLASH MRI technique. While spoiled ...

  7. Cardiac magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Cardiac_magnetic_resonance...

    Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2]

  8. Diffusion-weighted magnetic resonance imaging - Wikipedia

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

    Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that enables the measurement of the restricted diffusion of water in tissue in order to produce neural tract images instead of using this data solely for the purpose of assigning contrast or colors to pixels in a cross-sectional image.

  9. Digital subtraction angiography - Wikipedia

    en.wikipedia.org/wiki/Digital_subtraction...

    Intravenous digital subtraction angiography (IV-DSA) is a form of angiography which was first developed in the late 1970s.. IV-DSA is a computer technique that compares an X-ray image of a region of the body before and after radiopaque iodine based dye has been injected intravenously into the body.
