What is the Aber position?
True ABER position (a) as an apprehension (or stress) test for orthopedists entails 90° of abduction and 90° of flexion of the arm at the shoulder. During ABER positioning for MR arthography of the shoulder, the patient usually has to make >90° of abduction of the arm to fit into the magnet (b).
What is a Sublabral recess shoulder?
A superior sublabral recess is located at the 12 o’clock position and represents a normal recess between the superior labrum and the cartilage of the glenoid cavity. A sublabral foramen is located at the 2 o’clock position and represents localized detachment of the labrum from the glenoid rim.
What will an MRI show on my shoulder?
MRI gives clear views of rotator cuff tears, injuries to the biceps tendon and damage to the glenoid labrum, the soft fibrous tissue rim that helps stabilize the joint. MR imaging of the shoulder is typically performed to diagnose or evaluate: degenerative joint disorders such as arthritis and labral tears.
What is a glad lesion in shoulder?
A GLAD (glenolabral articular disruption) lesion is caused by a forced adduction injury to the shoulder from an abducted and external rotated position; patients with GLAD lesions present with anterior shoulder pain as their chief complaint.
How do you check for rotator cuff tear on MRI?
When examining using conventional MRI alone, T2-weighted images in the oblique coronal and oblique sagittal planes is the preferred technique for imaging the rotator cuff. Most radiologists have found that fat-suppressed, fast spin-echo, T2-weighted images are the most accurate for detecting rotator cuff tears.
What does white on a shoulder MRI mean?
The calcium is deposited within the rotator cuff which is part of the muscle that lifts up your arm. The calcium takes two forms – a chalk-like form which is hard and a toothpaste form which is almost liquid in nature. It is diagnosed on an x-ray where the calcium appears as white spots within the rotator cuff.
Can you see a torn labrum on an MRI?
In particular, MRI scans provide detailed pictures of soft tissue, including cartilage and the labrum. Doctors and radiologists at NYU Langone use three-dimensional MRI technology, which provides images of the hip joint from every angle and can reveal even the subtlest injury in the labrum or surrounding structures.
Can you see inflammation on an MRI?
MRI is an imaging method that is very sensitive in detecting inflammation and also bone erosions. This makes MRI an interesting tool to measure the course of the disease in randomised clinical trials and this suggests that MRI may also be useful in the diagnostic process.
Will Shoulder MRI show nerve damage?
Imaging, especially MRI, plays an important role to detect the underlying causes of nerve damage (extrinsic mass, rotator cuff tear, etc.), the precise topography of injury (involvement of both supraspinatus and infraspinatus muscles if the nerve is injured at suprascapular notch and isolated denervation sign of …
What is the Aber view of the shoulder?
The Abduction External Rotation (ABER) View for MRI of the Shoulder Jaideep J. Iyengar, MD; Keith R. Burnett, MD; Wesley M. Nottage, MD The ABER view is an excellent tool for detecting subtle soft tissue pathology of the anteroinferior labrum and rotator cuff and is strongly advocated for all contrast-enhanced imaging of the shoulder.
How is the Aber view used in a MRI?
The ABER view is an excellent tool for detecting subtle soft tissue pathology of the anteroinferior labrum and rotator cuff and is strongly advocated for all contrast- enhanced imaging of the shoulder. S houlder magnetic reso- nance imaging (MRI) is the gold standard imaging modality for evaluating soft tissue in the shoulder joint.
What is the Aber position of the rotator cuff?
In the ABER position the inferior glenohumeral ligament is stretched resulting in tension on the anteroinferior labrum, allowing intra-articular contrast to get between the labral tear and the glenoid. The ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff.
