Grading the severity of the rotator cuff tendinosis on MRI: Assessment of inter-observer agreement and evaluation of a novel objective assessment tool.

Introduction: MRI is generally considered the modality of choice for the assessment of rotator cuff pathology including tendinosis. Assessment of severity is currently subjective primarily based on tendon morphology and signal intensity. Limited data are available evaluating the inter-observer agreement regarding the assessment of tendinosis severity.

Endovascular management of recurrent hemarthrosis of the knee: a case series.

Background: Recurrent hemarthrosis of the knee is an uncommon but potentially debilitating occurrence with multiple etiologies, including previous total knee replacement. The purpose of this study is to present data of a group of patients undergoing angiography and embolization for recurrent hemarthrosis of the knee. Patient characteristics, angiographic findings, safety and efficacy of the procedure are reported.

Evaluation of the effect of double reporting on test accuracy in screening and diagnostic imaging studies: A review of the evidence.

Diagnostic error in radiology is not uncommon, with rates of clinically significant error reported to be as high as 20%. Radiological errors are often multifactorial, however, perceptual factors are thought to be mainly responsible. One way of reducing perceptual error is that of double reporting, which refers to the interpretation of radiological investigations by two observers, with strategies of arbitration and consensus available to settle discordant reports.
