Diagnostic value of Sonography and MR Imaging in rotator cuff for patients with shoulder pain
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 9
Abstract
Introduction: Ultrasonography(US) and magnetic resonance imaging (MRI) are both capable of diagnosing rotator cuff pathology. Objectives: To evaluate the diagnostic value of US and MRI in the detection of rotator cuff tears for patients with shoulder pain. Materials and methods: 87 patients with clinically suspected to have rotator cuff pathology underwent both US and MRI .The standard protocols of shoulder examinations were obtained. Sensitivity and accuracy of each modality have been evaluated and the correlation between the results of both imaging methods was deliberated using MRI as reference. The study included both genders, their mean age was 49.40± 12.4.The study spanned during the period from 2014-2017 Results: showed no significant difference in the diagnostic results of US and MRI. Sensitivity, and accuracy of the imaging methods were found to be: for Supra spinatous tendon partial tear ( 91%,91.6%)and(91%,92.8%) for US and MRI in respectively. Sensitivity and accuracy in diagnosis of Supra spinatous tendon full thickness tear were equal in both methods (100%, 100%) while Subscapularis tendon partial tear were (40%, 96.4%) and (100%, 96.1%) and Infa spinatous tendon partial tear (42%,95.4%) and (100%, 95.2%). The other non rotator cuff findings were found to have sensitivity ranged between (48%-100 %) and (29-92%) and accuracy ranged between (81.8% -98%) and (82.6-99%) for US and MRI in respectively Conclusions Regarding the comparable results; US proved to have high sensitivity and accuracy for full thickness tears with relatively less sensitivity in detection of partial thickness tear. Ultrasonography may be the suitable imaging method for diagnosis the rotator cuff tears when the examiner has been well trained and we recommended to be used as the first line imaging modality in evaluation of shoulder pain as it is sensitive , accurate, cheap and available, as well; for practitioners without ultrasound expertise, MRI can be used.
