Shoulder MRArthrography was performed to get an accurate diagnosis about complex anatomical structure in shoulder joint. We carried out how the changes of anatomical rotations in shoulder joint could bring certain diagnosis effects on MRI images for various shoulder humerus positions; Neutral position, Internal rotation position and External rotation position. In addition, we prepared an aid tool in oder to maintain the right posture of a patient. This aid tool was made by adapting Modeling Design Program. By virtue of this aid, we obtained the following result. Shoulder MR Arthrography by the External rotation position for anatomical structure diagnosis was the most suitable in diagnostic evaluations of important anatomical structures in shoulder joint such as Biceps tendon, Supera-spiatus tendon, Sub-scapularis tendon, Labrum and Sub-acromial space.

Adhesive capsulitis, the so-called 'frozen shoulder', is one of the common causes of pain with a limited range of motion in the shoulder joint. The condition is usually diagnosed through the clinical course and physical examinations; however, several studies on imaging findings of adhesive capsulitis using sonography, MRI, and MR angiography have been reported. In this article, various imaging findings for the diagnosis of adhesive capsulitis-related anatomy are reviewed.

Purpose: The purpose of this study was to assess the efficacy of MR arthrography to detect partial thickness rotator cuff tears. Materials and Methods: One hundred and seventy seven patients with a high suspicion for rotator cuff disease were studied by performing MR-arthrography and subsequent arthroscopy. The ability of MR-arthrography to detect partial thickness tears was evaluated according to the location of the tears. We determined the correspondence between the measurements of the articular side partial tears on MR arthrography and those on the arthroscopic findings. Results: The arthroscopic diagnosis of partial thickness rotator cuff tears was divided into 3 groups according to their location. There were 63 cases on the articular side, 41 cases on the bursal side and 20 cases on both sides. The sensitivity of MR-arthrography was 82% for the articular side tears and 11% for the bursal tears. The specificity was 88% for the articular side tears and 100% for the bursal tears. MR-arthrographic measurement correctly predicted 72% in 28 repaired cases of 56 articular side partial thickness tears. Conclusions: MR-arthrography may be a reliable tool for diagnosing articular side partial thickness rotator cuff tears, but it has limitations for bursal side tears.

Ultrasonography is a powerful and useful method for the examination of the various shoulder diseases. The use of high-resolution transducer and technical evolution allowed the improvement of the accuracy of detection of the rotator cuff disease. However, its limitation is that there is marked disparity in the interpretation according to the operators' experience. This article describes the ultrasonographic findings of rotator cuff pathology compared to the MR (magnetic resonance) imaging and arthroscopic findings for helping the interpretation of ultrasonographic picture.
