Volumetric Breast Density Assessment: Reproducibility in Serial Examinations and Comparison with Visual Assessment

Volumetric Breast Density Assessment: Reproducibility in Serial Examinations and Comparison with Visual Assessment Volumetrische Bestimmung der Brustdichte: Reproduzierbarkeit in seriellen Mammografie-Untersuchungen und Vergleich mit visueller Dichtebestimmung

Hintergrund und Zielsetzung: Die mammografische Brustdichte ist der stärkste bekannte Marker des Brustkrebsrisikos. Visuell-erhobene Brustdichtebestimmung unterliegt einer großen Intraund Interrater-Variabilität. Ziel der aktuellen Studie war es die Reproduzierbarkeit der automatischen Brustdichtebestimmung zu testen und die Ergebnisse mit der visuellen Dichtebestimmung zu vergleichen. Patiente...

assessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...

Visual assessment of breast density in mammograms

Factors Affecting Agreement between Breast Density Assessment Using Volumetric Methods and Visual Analogue Scales

Mammographic density in digital mammograms can be assessed visually or using automated volumetric methods; the aim in both cases is to identify women at greater risk of developing breast cancer, and those for whom mammography is less sensitive. Ideally all methods should identify the same women as having high density, but this is not the case in practice. 6422 women were ranked from the highest...
