Our goal is to provide an overview of common normal variants of the shoulder's anatomical structures as well as any associated clinical or surgical relevance.</p><p><strong>Material and methods: </strong>Following a literature search of common variants of the shoulder and supporting structures, this review provides a summary of variants related to the scapular body, acromion, glenoid, coracoid, labrum, long head biceps tendon, glenohumeral ligamentous complex, and rotator cuff.</p><p><strong>Results and conclusion: </strong>The shoulder is composed of the glenohumeral, acromioclavicular, sternoclavicular, and scapulothoracic joints and their associated osseous, ligamentous, cartilaginous, and musculotendinous stabilizers.

An awareness of associated pathological conditions and an understanding of when variants might be clinically significant is important in interpreting radiological exams.</p><p><strong>Key points: </strong>· Normal variants of the shoulder are commonly encountered when interpreting imaging exams, especially in the adolescent and young adult population. We describe some of the more clinically relevant variants of the glenohumeral joint.. · Meso-acromion os acromiale is the by far the most common type followed by the pre-acromion type.. · While an os acromiale is commonly asymptomatic; acromial apophysiolysis is typically symptomatic and may result in future development of an os acromiale.. · The glenoid bare area is typically small and near the center of the glenoid, which helps differentiate it from a pathological cartilaginous lesion.. · The middle glenohumeral ligament has the most variability, and it is absent in nearly 40% of patients..</p><p><strong>Citation format: </strong>· Haug LP, Shah AS, Shrestha R et al.

Dose metrics (CTDIvol, DLP, SSDE, effective dose) were extracted using automated dose monitoring.

The median intra-individual radiation dose variability was 93.7% (IQR 19.8-142.0%) in non-contrast chest CT, 66.3% (31.1-105.4%) in contrast-enhanced chest CT, 19.8% (11.8-32.3%) in non-contrast abdominal CT, and 28.2% (16.6-41.0%) in contrast-enhanced abdominal CT.
