Abstract
Shoulder pain is considered one of the commonest
musculoskeletal complaints presented to orthopedics and
rheumatologists. It is commonly affected by degenerative
changes, overuse and traumatic lesions.
Many imaging techniques could be used in the
assessment of painful shoulder joint, including plain
radiographs, computerized tomography, magnetic resonance
imaging and high-resolution ultrasonography.
High resolution ultrasonography has advantages over
other modalities in term of patient comfort, availability, low
cost compared to CT and MRI, in addition to its diagnostic
potential; its ability to be performed in real time for
correlation with the exact site of patient complaint,
comparison with the other healthy side, dynamic evaluation,
its high resolution and power Doppler evaluation of different
lesions.
Ultrasonography also shows no hazards of radiation
exposure compared to CT and plain radiographs, and no
contraindications compared to MRI studies as for patients
with pace makers.
The aim of our study was to evaluate degree of intermethod
agreement between high resolution ultrasonography
and MRI in assessment of rotator cuff pathologies.
This study included 52 patients, ranging in age from
19 to 78-year-old. They were referred to a private center,
during the period from june to november 2018.
Those patients were examined by high resolution
ultrasound and MRI.
Summary and Conclusion
123
In our study, high resolution ultrasonography could
successfully diagnose many patients with soft tissue lesions.
The main limitations were the assessment of bone marrow,
deep articular cartilage, and soft tissue
Both modalities, ultrasound and MRI, has almost
equivalent ability in the evaluation of superficial structures
such as tendons. The proper choice between one of them is
determined according to; availability, referring clinician and
the presence of a well-trained operator.
Ultrasound is superior to MRI in the evaluation of soft
tissue abnormalities adjacent to hardware, and in the
evaluation of abnormalities that require certain dynamic
movement or positioning to provide a proper diagnosis
