BACKGROUND The primary objective of this study was to assess the interobserver and intraobserver agreement on ligamentous injuries on conventional magnetic resonance imaging (MRI) in acute simple elbow dislocation. The secondary objectives were to determine the interobserver agreement on the assessment of joint congruity, joint effusion, loose bodies and chondral lesions on conventional MRI. ...

We studied the reproducibility of ultrasonographic screening examination of the hip when read by diagnostic radiographers. In order to determine interobserver variability, 200 ultrasonograms were classified according to Graf's method by five observers (four radiographers and one radiologist). The kappa values for interobserver variability indicated moderate agreement (kappa 0.47) for the exact ...

Interobserver reliability of the Teller acuity card (TAC) procedure for estimating acuity and interocular acuity differences (IADs) was assessed with 342 infants and children who had been treated in a neonatal intensive care unit for preterm birth and/or perinatal complications. Subjects were tested binocularly at term and monocularly at 4, 8, 11, 17, 24, 30, 36, and 48 months corrected age wit...

Plain radiographs are commonly used to evaluate the degree of bone healing after an osteotomy and the application of an external fixator. The purpose of the study was to assess intraobserver and interobserver reliability in determining bone healing, defined as bridging callus across three of four cortices, of osteotomy sites on radiographs. Substantial intraobserver reliability and a high intra...

The aim of this study was to assess interobserver agreement of ultrasound parameters for portal hypertension in hepatosplenic mansonic schistosomiasis. Spleen size, diameter of the portal, splenic and superior mesenteric veins and presence of thrombosis and cavernous transformation were determined by three radiologists in blinded and independent fashion in 30 patients. Interobserver agreement w...

OBJECTIVE The AO classification for fractures of the long bones in the pediatric population was developed and validated in 2006. However, the complexity of this system has limited its use in clinical practice and few studies in the literature have evaluated its reproducibility and applicability. The present study had the objective of determining the intra and interobserver agreement using the p...

Existing indices of observer agreement for continuous data, such as the intraclass correlation coefficient or concordance coefficient, measure total observer-related variability, which includes variabilities between and within observers. This work introduces a new index that measures interobserver is defined in terms distances among ‘true values’ assigned by different observers on same subject....
