OBJECTIVE The purpose of this study was to compare the diagnostic accuracy of MRI, MR arthrography, and ultrasound for the diagnosis of rotator cuff tears through a meta-analysis of the studies in the literature. MATERIALS AND METHODS Articles reporting the sensitivities and specificities of MRI, MR arthrography, or ultrasound for the diagnosis of rotator(More)
PURPOSE To determine the sensitivity and specificity of ultrasonography (US) in the detection of lateral epicondylitis and identify the US findings that are most strongly associated with symptoms. MATERIALS AND METHODS Internal review board approval was obtained for retrospective review of the patient images, and the need for informed consent was waived.(More)
OBJECTIVE Spatial compound sonography is a method that obtains sonographic information from several different angles of insonation and combines them to produce a single image. By reducing speckle and improving definition of tissue planes, this method can potentially improve image quality in musculoskeletal sonography. The purpose of our study was to compare(More)
RATIONALE AND OBJECTIVES The authors compared Doppler ultrasound (US) with computed tomographic (CT) angiography in the evaluation of stenosis of the main renal artery. MATERIALS AND METHODS Fifty-six patients who had undergone conventional angiography of the renal arteries participated in a prospective comparison of Doppler US (45 patients) and CT(More)
PURPOSE To determine whether dynamic ultrasonography (US) can reveal abnormalities of the anterior band of the ulnar collateral ligament (UCL) of the elbow in asymptomatic major league professional baseball players. MATERIALS AND METHODS US was performed in 26 asymptomatic major league professional baseball pitchers before spring training. Images were(More)
OBJECTIVE As an alternative to traditional surgical transrectal and transgluteal drainage, we have examined the efficacy of transrectal sonographically guided drainage for deep pelvic abscesses not accessible by percutaneous transabdominal or transvaginal routes. SUBJECTS AND METHODS In nine patients (five males and four females) 5-51 years old,(More)
OBJECTIVE Worldwide, the use of sonography for the evaluation of the musculoskeletal system has been growing. However, radiologists in North America have been relatively slow to incorporate musculoskeletal sonography into their practices. The purpose of this article is to show the advantages of musculoskeletal sonography. CONCLUSION Musculoskeletal(More)
PURPOSE To compare results of helical computed tomographic (CT) angiography with real-time interactive volume rendering (VR) to CT angiography with maximum intensity projection (MIP) for the detection of renal artery stenosis. MATERIALS AND METHODS Twenty-five patients underwent both conventional and CT angiography of the renal arteries. Images were(More)
BACKGROUND Nonsurgical management of de Quervain's tenosynovitis often includes corticosteroid injections. If the injection does not enter the compartment, or all subcompartments, response to the injection is variable. To ensure proper location of injections we evaluated the role of ultrasound. QUESTIONS/PURPOSES We determined (1) the incidence of two or(More)
BACKGROUND An injury to the ulnar collateral ligament (UCL) of the elbow is potentially career threatening for elite baseball pitchers. Stress ultrasound (US) of the elbow allows for evaluation of both the UCL and the ulnohumeral joint space at rest and with stress. HYPOTHESIS Stress US can identify morphological and functional UCL changes and may predict(More)
