ABduction and External Rotation (ABER) sequence in magnetic resonance (MR) arthrography of the shoulder is particularly important to better depict abnormal conditions of some glenohumeral joint structures and surrounding tissues by making imaging ...

The ABER (Abduction and External Rotation) view in MRI is a specialized imaging sequence used primarily in shoulder MR arthrography to evaluate the glenohumeral joint and surrounding structures under stress.

Apr 2, 2012 · The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 o'clock position, where most labral tears are located.

Mar 5, 2019 · MRI MSK adult shoulder arthrogram protocol for adult patients. Kept current by Radiologists and Technologists.

Oct 25, 2019 · The ABER position relates to MR arthrography of the shoulder joint and is a mnemonic for AB duction and E xternal R otation. In this position, labral tears are made conspicuous by tightening the inferior glenohumeral labroligamentous complex (which are also the most important glenohumeral ligaments in preventing shoulder instability).

Nov 23, 2012 · In this article, we review the technique and normal anatomy of the ABER view and provide examples of several abnormalities for which the ABER view is helpful in diagnosing. After conventional MR sequences are performed, the patient is repositioned in ABER with the hand placed behind the head or neck and the elbow flexed (Fig. 1A).

May 29, 2024 · The MRI shoulder protocol encompasses a set of different MRI sequences for the routine assessment of the shoulder joint. Note: This article aims to frame a general concept of an MRI protocol for the assessment of the shoulder joint.

Key points: · ABER-MRA is useful in the evaluation of pathologies of the anteroinferior labroligamentous complex. · ABER-MRA does not increase sensitivity or specificity with regard to rotator cuff tears. · ABER-MRA may be helpful for the detection of SLAP lesions and micro-instability in overhead athletes.

Several (usually two or three) scout series have to be obtained to allow proper imaging plane alignment for the ABER sequence. The relatively short time spent for these scout series will pay off with the proper acquisition of ABER (T1-weighted fat-saturated) MR images.

ABduction and External Rotation (ABER) sequence is particularly important to better depict abnormal conditions of some glenohumeral joint structures and surrounding tissues by rendering possible imaging under a stress position relevant to pathologic conditions.
