The diagnostic reliability of sonoelastography in rotator cuff disorders in comparison with MRI findings in patients suffering from shoulder pain
摘要
It is commonly known that, when done by qualified sonographers, magnetic resonance imaging (MRI) and conventional sonography are diagnostically equivalent in diagnosing rotator cuff disorders. The purpose of this study was to examine the accuracy of shear wave elastography in identifying various rotator cuff diseases in patients presenting with shoulder pain in relation to magnetic resonance imaging results; as the shear wave elastography is an emerging non-invasive technique for the evaluation of the stiffness and elasticity of soft tissues, and there is growing evidence for the use of elastography in the musculoskeletal system due to the obvious clinical advantages; nevertheless, the dynamic nature of muscles and a lack of scan protocols make this a challenging topic.
Aim of studyIn this prospective study, we aimed to assess the role and the degree of reliably shear wave elastography in detecting rotator cuff pathologies in patients complaining of acute or chronic shoulder pain, compared to MRI findings with a correlation between the recorded velocities and MRI grading.
ResultsShear wave elastography has a rotator cuff injury detection sensitivity of 87.5%, a specificity of 100%, and an accuracy of 94.44%. Shear wave velocity was greater in rotator cuff tendinopathy than in tears (2.90 ± 0.23 m/sce2 vs. 2.43 ± 0.44 m/sec2; p = 0.001). The velocities of tenosynovitis patients were significantly higher (6.27 ± 0.86 m/sec2) than those of control biceps tendons, tendinosis (2.90 ± 0.42 m/sec2), and cases of combined tenosynovitis and tendinopathy (2.27 m/sec2). In both advanced and early degrees of rotator cuff diseases, MRI and US approaches were comparable, with a highly significant negative connection between the grade of tendon affection and SWE measures.
ConclusionsWhen MRI is inaccessible, ultrasound and SWE can be utilized as non-invasive, sensitive, and reasonably priced modalities to identify rotator cuff pathology. They can also be helpful in the preoperative evaluation for tendon tears to enhance prognosis and avoid re-tearing.
