[en] Objective: To evaluate the conventional arthrography(CA), CT arthrography(CTA), and MR arthrography (MRA) in diagnosis of traumatic rotator-cuff tears of the shoulder. Methods: Twenty patients with traumatic rotator-cuff tears confirmed by arthroscopy were retrospectively reviewed in this study. Glenohumeral joints were punctured percutaneously under fluoroscopic guidance, and 15-20 ml of mixed contrast were injected [10 ml of iodinated contrast (Omnipaque) mixed with 20 ml of 3 mmol/L gadopentetate dimeglumine solution(3 ml of 0.5 mol/L Magnevist in 500 ml of normal saline)] ,and then CA, CTA and MRA was taken within 45 minutes. Result: 100% (9/9) of diagnostic accuracy was obtained in any of conventional, CT or MR shoulder arthrography in the state of complete tears. However, the accuracy of CA,CTA or MRA was 27.3% (3/11), 18.2% (2/11), 66.7% (7/11)respectively in the state of partial tears. Conclusion: MRA is more effective to demonstrate the rotator cuff tears compared to CA or CTA
