Intra-observer, inter-observer and inter-scanner variations in brain MRI volume measurements in multiple sclerosis.
INTRODUCTION Measurement of brain volume on magnetic resonance imaging (MRI) scans is regarded as an objective marker of multiple sclerosis (MS) severity with the potential to monitor treatment efficacy accurately. This study was performed to assess the variability of brain MRI volume measurements. PATIENTS AND METHODS We studied nine patients with relapsing-remitting MS, who were imaged on t...
متن کاملInter-observer variations in FDG-PET interpretation for cancer screening.
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.

However one can judge how much confidence to place in one's results by assessing the reliability of the records of one's variables. In this paper we shall consider only inter-observer reliability or score...
متن کاملinter-observer and intra-observer agreement in pathological evaluation of non-alcoholic fatty liver disease suspected liver biopsies
results inter-observer agreement of the pathology scores based on nas scoring system was acceptable for steatosis, lobular inflammation, and fibrosis, but not for hepatocyte ballooning. the intra-observer agreement was acceptable in all scales, with lowest intra-class correlation observed for lobular inflammation. materials and methods the anonymous liver biopsy samples of 100 consecutive nafld...
