BACKGROUND The impact of a recurrent defect on the outcome after rotator cuff repair has been controversial. The purpose of this study was to evaluate the functional and anatomic results after arthroscopic repair of large and massive rotator cuff tears with use of ultrasound as an imaging modality to determine the postoperative integrity of the repair.

BACKGROUND Although many investigators have evaluated the accuracy of ultrasonography and magnetic resonance imaging for the detection of full and partial-thickness rotator cuff tears, few have directly compared the two tests. The purpose of our study was to compare the accuracy of the two tests for detection and measurement of the size of rotator cuff(More)
BACKGROUND Double-row arthroscopic rotator cuff repairs were developed to improve initial biomechanical strength of repairs to improve healing rates. Despite biomechanical improvements, failure of healing remains a clinical problem. PURPOSE To evaluate the anatomical results after double-row arthroscopic rotator cuff repair with ultrasound to determine(More)
BACKGROUND There has been limited acceptance of shoulder ultrasonography by orthopaedic surgeons in the United States. The purpose of this retrospective study was to determine the diagnostic performance of high-resolution ultrasonography compared with arthroscopic examination for the detection and characterization of rotator cuff tears. METHODS One(More)
BACKGROUND It has been theorized that degenerative rotator cuff tears most commonly involve the supraspinatus tendon, initiating at the anterior portion of the supraspinatus insertion and propagating posteriorly. The purposes of this study were to determine the most common location of degenerative rotator cuff tears and to examine tear location patterns(More)
PURPOSE To determine and compare the diagnostic performance of computed tomography (CT), magnetic resonance (MR) imaging, ultrasonography (US), and positron emission tomography (PET) in the detection of hepatocellular carcinoma (HCC) or cholangiocarcinoma in liver transplant candidates and to determine interobserver variability between the readers.

PURPOSE To analyze whether shadowing and other ultrasound (US) features were helpful for distinguishing angiomyolipoma (AML) from renal cell carcinoma (RCC). MATERIALS AND METHODS US images were reviewed of 49 patients with RCC and 35 patients with AML. Each tumor was evaluated for size, location, echogenicity, homogeneity, shadowing, hypoechoic rim, and(More)
OBJECTIVE Our purpose was to determine the overall accuracy of Doppler sonography and the accuracy of specific Doppler parameters associated with a compromised transjugular intrahepatic portosystemic shunt (TIPS). MATERIALS AND METHODS For 43 patients who had undergone TIPS, 64 correlated sonogram-venogram paired examinations were analyzed. Sonographic(More)
PURPOSE To determine in patients with testicular microlithiasis (TM) the short-term natural history of classic TM (CTM) and limited TM (LTM). MATERIALS AND METHODS In 104 patients, testicular microliths were identified on ultrasonographic (US) images; 39 patients had five or more microliths on at least one US image (criterion for CTM), and 65 patients had(More)
OBJECTIVE To determine the relative benefit of staging laparoscopy in peripancreatic and biliary malignancies. SUMMARY BACKGROUND DATA Staging laparoscopy has been used in a variety of peripancreatic and biliary malignancies. The utility of the technique in subsets of these types of cancer has not been systematically compared. METHODS One hundred(More)
