Comparison of magnetic resonance and ultrasound in the diagnosisof long head of the biceps tendon injury / 实用放射学杂志

ABSTRACT

Objective To investigate MR and US diagnotic value of long head of the biceps tendon injury.Methods A total of 80 patients with suspected injury of long head of the biceps tendon underwent arthroscopy surgery.All patients had MR and US examination preoperatively.The preoperative results were compared with the findings during the arthroscopy in order to assess the effectiveness of two methods.Results Among 80 patients, there were completely torn in 19 cases, partly torn in 45 cases, biceps tendon tenosynovitis in 10 cases, biceps tendon slippage in 6 cases.The accuracy of MR and US in the diagnosis of completely torn, partly torn, biceps tendon tenosynovitis, biceps tendon slippage were 98.7%,92.5%,97.5%,100% and 96.2%,85.0%,96.3%,98.7% respectively.There was no statistic difference between MR and US in diagnosing completely torn,biceps tendon tenosynovitis and biceps tendon slippage(P>0.05),but the accuracy of MR in diagnosing partly torn was higer than US(P<0.05).Conclusion MR determination of biceps tendon partial tear is of obvious advantages.US examination can be used as a routine method for the investigation of patients with suspected biceps tendon injury.
