Inter-rater reliability in the classification of supraspinatus tendon tears using 3D ultrasound – a question of experience?

Abstract
Three-dimensional (3D) ultrasound of the shoulder is characterized by a comparable accuracy to two-dimensional (2D) ultrasound. No studies investigating 2D versus 3D inter-rater reliability in the detection of supraspinatus tendon tears taking into account the level of experience of the raters have been carried out so far.
