简要总结
This study aims to assess the efficacy of three-dimensional magnetic resonance (MR) compared to three-dimensional computed tomography (CT) imaging. This proposed study is a prospective, unrandomized, single-blinded, self-controlled, and single-armed diagnostic radiological evaluation study.

Glenoid Inclination
时间窗: 3 Months
The 3D MRI glenoid inclination is measured by the two observers with the same method used for CT 3D glenoid inclination measurement following generating a new 2D axial MR images form the 3D MRI model using the three-point method. A line on the supraspinatus fossa and 3 points are drawn: Point S represents the inferior border of the glenoid, point R represents the intersection of the supraspinatus fossa line with the glenoid surface, and point A represents the vertex of the right triangle created by the line of the supraspinatus fossa and a perpendicular line passing through point S; this line (RS) is the hypotenuse of the right triangle. The inclination corresponds to the area in which the glenoid component of RSA is implanted.
Glenoid Version
时间窗: 3 Months
All scans from 3D CT and 3D MR imaging were reviewed carefully for the presence of any morphological changes. For the determination of glenoid version, a line was drawn between the anterior and posterior margins of the glenoid. The transverse axis of the scapula was determined by a line drawn from the midpoint of the genoid fossa to the medial end of the image of the scapula; a line drawn perpendicular to this was defined as a line of neutral version. The angle between the line of neutral version and the line connecting the anterior and posterior margins of the glenoid was measured and recorded as the Glenoid Version.
