Results Intra-observer variability was assessed using intraclass correlation coefficient (ICC); inter-observer variability was assessed using Bland Altman plots for agreement. Intra-observer variability was low for both observers (ICC; observer 1 EDV: 0.99, ESV: 0.93, mass: 0.94 vs observer 2 EDV: 0.97, ESV: 0.97, mass: 0.94). Interobserver variability was lowest for volumes and highest for mas...

BACKGROUND The purpose of the study was to evaluate inter- and intra-observer variability in sonographic measurements of the cross-sectional area of the umbilical cord and the diameters of its vessels in low-risk pregnancies of 12 to 40 weeks of gestation. METHODS A prospective cross sectional study was performed in 221 pregnant women at different gestational ages. Measurements were carried o...

BACKGROUND Diagnostic guidelines for the use of 2-(fluorine 18) fluoro-2 deoxy-D-glucose (FDG)-positron emission tomography (PET) in cancer screening have yet to be established. We assessed inter-observer variability in screening FDG-PET. METHODS Subjects comprised 40 individuals who underwent FDG-PET and computed tomography (CT) for cancer screening. To assess various patterns of FDG uptakes...

STUDY QUESTION Does the use of diagnostic criteria in the hysteroscopic diagnosis of a septate uterus improve inter-observer agreement? SUMMARY ANSWER Pre-set diagnostic criteria slightly improve the inter-observer reproducibility of hysteroscopy in diagnosing a uterine septum, although agreement remains moderate. WHAT IS KNOWN ALREADY The inter-observer agreement on the hysteroscopic diagn...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...

OBJECTIVES To evaluate inter-observer agreement for microscopic measurement of inflammation in synovial tissue using manual quantitative, semiquantitative and computerised digital image analysis. METHODS Paired serial sections of synovial tissue, obtained at arthroscopic biopsy of the knee from patients with rheumatoid arthritis (RA), were stained immunohistochemically for T lymphocyte (CD3) ...

INTRODUCTION It is important to create a body of evidence surrounding the reliability of certain diagnostic criteria. While the reliability of the Cobb measurement is well established with various licensed health care professionals, this study aims to determine the inter- and intra-observer reliability of the Cobb Measurement among chiropractic interns. METHODS Fourteen chiropractic interns a...
