ABSTRACT
Background: A rotator cuff tear is a tear of one or more of the tendons of the four rotator cuff muscles of the shoulder. The rotator cuff is a group of muscles that play an important role in function of the glenohumeral joint. Value of the clinical examination of a shoulder is often uncommonly exhibited; therefore, imaging modalities have valuable implications in the management of rotator cuff pathologies
Aim: the purpose of this study is to assess the diagnostic accuracy of MRI in diagnosis of rotator cuff tears
Materials and Methods: we examined 20 consecutive cases of shoulder arthroscopy, who had undergone preoperative investigation in the form of MRI. Comparing the accuracy of MRI for detection of full-thickness rotator cuff tears, using the operative findings as the 'gold standard' was used. All the patients presented to Radiology Department referred from Orthopedic Outpatient Clinic, El-Demerdash University Hospital and Nassir Institution, from January 2017 to October 2017
Results: 16[80%] were males, 4[20%] were females, with age range from [27y] to [57y] [mean range 42y] complaining of symptoms and signs of shoulder pain which go more with RCT The overall accuracy of MRI in diagnosis of RCT, was 99%, while sensitivity and specificity was 99%,98.8] respectively, with P value less than 0.05
Conclusion: MRI is an accurate diagnostic imaging method for RCT specially for the FTT, and considered to be best cost-effective, non-invasive imaging method for screening of rotator cuff tears .In patients who underwent surgery, MRI yielded comparably high sensitivity for detecting full-thickness RCT
