2-dimensional shear wave elastography: Interobserver agreement and factors related to interobserver discrepancy
PURPOSE To evaluate the interobserver reproducibility of two-dimensional shear wave elastography (2D-SWE) in measuring liver stiffness (LS) and to investigate factors related to liver 2D-SWE. MATERIALS AND METHODS A prospective study was conducted between August 2011 and August 2012 in rheumatoid arthritis patients who had been treated with methotrexate. Interobserver reproducibility of 2D-SW...
متن کاملUnderstanding interobserver agreement: the kappa statistic.
Items such as physical exam findings, radiographic interpretations, or other diagnostic tests often rely on some degree of subjective interpretation by observers. Studies that measure the agreement between two or more observers should include a statistic that takes into account the fact that observers will sometimes agree or disagree simply by chance. The kappa statistic (or kappa coefficient) ...
متن کاملInterobserver agreement after pipeline embolization device implantation.
BACKGROUND AND PURPOSE Although flow diversion devices are popular in treatment of aneurysms, angiographic assessment with these devices has rarely been verified by interobserver variability study. The purpose of this study was to determine the interobserver agreement of a 3-point grading system for assessing the angiographic outcome after flow diversion therapy of intracranial, saccular aneury...
متن کاملThree dimensional shear wave scattering MR elastography
Introduction: Magnetic resonance elastography (MRE) is a non invasive method that combines externally applied vibrations with the motion sensitivity of MRI to measure the shear elasticity soft tissues [1]. In MRE this is traditionally achieved by solving an inverse problem with MRE shear wave images as input data [2]. A complementary approach, which does not require the solution of an inverse p...
متن کاملInterobserver agreement of EUS elastography in the evaluation of solid pancreatic lesions
BACKGROUND AND OBJECTIVES Previous reports assessing the reproducibility of endoscopic ultrasound elastography (EUS-E) in evaluation of solid pancreatic lesions (SPL) involved only experienced endosonographers. We aimed to assess the interobserver agreement (IOA) of EUS-E in the evaluation of SPL by endoscopists with different levels of experience in EUS and EUS-E. MATERIALS AND METHODS A cro...
