The lesion is associated with any damage to the antero-inferior labrum. Most commonly due to anterior shoulder dislocation. The lesion often occurs after the initial dislocation. In chronic cases, there may be fibrosis and resynovialization of the labrum and periosteum. [citation needed] The lesion is best identified on MR arthrography.
MRI of normal shoulder intratendinous signal MRI of rotator cuff full-thickness tear. Magnetic resonance imaging and ultrasound [46] are comparable in efficacy and helpful in diagnosis, although both have a false positive rate of 15–20%. [47] MRI can reliably detect most full-thickness tears, although very small pinpoint tears may be missed.
Neuroimaging, usually with computed tomography (CT/CAT) or magnetic resonance imaging (MRI), is used to exclude any mass lesions. In IIH these scans typically appear to be normal, although small or slit-like ventricles , dilatation and buckling [ 18 ] of the optic nerve sheaths and " empty sella sign " (flattening of the pituitary gland due to ...
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [3] It is an injury of the anterior ( inferior ) glenoid labrum of the shoulder. [ 4 ] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.
Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images.

MRI has become the most frequently used study to diagnose spinal stenosis. The MRI uses electromagnetic signals to produce images of the spine. MRIs are helpful because they show more structures, including nerves, muscles, and ligaments than seen on X-rays or CT scans. MRIs are helpful in showing exactly what is causing spinal nerve compression.
