  2. Adhesive capsulitis of the shoulder - Wikipedia

    It is also widely available, convenient, and cost efficient. Thickening in the coracohumeral ligament, inferior capsule/ axillary recess capsule, and rotator interval abnormality, as well as restriction in range of motion in the shoulder can be detected using ultrasound. The range of motion is prohibited due to scapulohumeral rhythm changes ...

  3. Shoulder joint - Wikipedia

    en.wikipedia.org/wiki/Shoulder_joint

    Axillary pouch of the shoulder can be seen on external rotation, while subscapular (subcoracoid) bursa can be seen on internal rotation of arm. The contrast should not enter subacromial bursa unless supraspinatus tendon is completely ruptured. [4] MRI with surface coils is used to image the shoulder joint. [4]

  4. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    A contrast agent usually shortens, but in some instances increases, the value of T1 of nearby water protons thereby altering the contrast in the image. Most clinically used MRI contrast agents work by shortening the T1 relaxation time of protons inside tissues via interactions with the nearby contrast agent.

    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. Phase contrast magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Phase_Contrast_Magnetic...

    Phase contrast MRI is one of the main techniques for magnetic resonance angiography (MRA). This 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. MRA is often used to evaluate ...

  7. Diffusion-weighted magnetic resonance imaging - Wikipedia

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

    When water is in an environment where it can freely tumble, relaxation tends to take longer. In certain clinical situations, this can generate contrast between an area of pathology and the surrounding healthy tissue. To sensitize MRI images to diffusion, the magnetic field strength (B1) is varied linearly by a pulsed field gradient.

  8. Axilla - Wikipedia

    en.wikipedia.org/wiki/Axilla

    The axilla (pl.: axillae or axillas; also known as the armpit, underarm or oxter) is the area on the human body directly under the shoulder joint.It includes the axillary space, an anatomical space within the shoulder girdle between the arm and the thoracic cage, bounded superiorly by the imaginary plane between the superior borders of the first rib, clavicle and scapula (above which are ...

  9. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
