- Shoulder pain is one of the commonest conditions encountered in our orthopedic department. Accurate diagnosis is a must before undertaking any treatment. Since clinical diagnosis cannot make an accurate diagnosis, radiological investigation is necessary to know the exact cause of shoulder pain. There are a wide range of invasive and noninvasive modalities that can be used to investigate these patients. Ultrasound examination is a highly specific and sensitive modality in comparison with MRI.
