Radiographic Union Score for Tibia (RUST) scoring system in adult diaphyseal femoral fractures treated with intramedullary nailing: an assessment of interobserver and intraobserver reliability
… Our objective was to assess the inter and intraobserver reliability for the RUST in diaphyseal femoral fractures treated with intramedullary (IM) nailing. Patients and Methods A total of 60 sets of anteroposterior (AP) and lateral radiographs of diaphyseal femoral fractures treated by …

Assessment of the interobserver and the intra observer reproducibility for the detection of renal cortical defects in adults and children using [99mtc]Tc-MAG3
… renography. We aim to assess interobserver and intraobserver reproducibility for detecting renal cortical defects using [ 99mTc]Tc-MAG3 for adults and children; identify causes for poor inter- and intraobserver reproducibility and to assess the effect of the kidney to background ratio (KTBR) on …

Analyzing the Consistency of Scoring Porotic Hyperostosis From 3D Scans
… from 25 3D scans on three separate days. Intraobserver and interobserver error tests were performed to determine if there were any patterns in the researchers’ scores. In addition, the data for each of the 25 scans were examined to determine if the quality of the scans influenced the …

Perspectives on the management of humerus fractures due to gunshot trauma: an inter- and intra-observer agreement and reliability study
… The primary aim was to assess the inter- and intraobserver agreement between surgeons in the classification and treatment of humerus fractures caused by gunshot trauma in a gunshot violence endemic area. The secondary aims were to analyse interobserver agreement with respect to debridement, …

Hochaufgelöste cine-Magnetresonanz-Bildgebung des Mäuseherzens zur Bestimmung rechtsventrikulärer Morphologie und funktioneller Parameter : Validierung der Methode und Etablierung an zwei Modellen der Herzinsuffizienz
… zeigte ein hohes Maß an Reproduzierbarkeit (intraobserver- und interobserver-Variabilität jeweils <7%). Die MR-Messung 4 Wochen nach Pulmonalbanding ergab einen signifikanten Anstieg des RV enddiastolischen Volumens (+44%, p<0.005) und vor allem RV endsystolischen Volumens (+133%, p<0.0001). …

Quantitative Untersuchungen zur Biometrie des vorderen Augenabschnittes
… auch Nachteile gegenüber; so ist bei guter Intraobserver-Reproduzierbarkeit eine deutliche Schwäche bezüglich der Interobserver-Reproduzierbarkeit festzustellen, dies ließe sich durch eine exaktere Meßpunktdefinition sicherlich noch verbessern. Dies ist auch erforderlich zur …

Thoracic Radiotherapy Treatment Planning With Cine Pet/Ct
… tumors respectively which was within intraobserver variation. Dose distributions on cine CT produced good agreement (< 2%/1 mm) with 4D-CT for 71 of 73 patients. The segmentation model fit the phantom data with R2 = 0.96 and produced PET target volumes that matched CT better than 6 …

Novel positron emission tomography applications for imaging cardiovascular disease activity
… There was excellent intraclass correlation for intraobserver and interobserver repeatability as well as interscan reproducibility (all ≥0.991). There was 100% intraobserver, interobserver and interscan agreement for the presence (CMA>0) or absence (CMA=0) of coronary18F-sodium fluoride uptake. …

Vergleich unidimensionaler, bidimensionaler und volumetrischer Messverfahren unter Anwendung eines 64-Zeilen-Mehrschicht-CTs am Beispiel von Bronchialkarzinomen und pulmonalen Metastasen
… Zur Beurteilung der Reproduzierbarkeit wurde ein Intraobserver-Vergleich angestellt. Dieser kam zu dem Ergebnis, dass der relative Messfehler bei der Volumetrie mittels Region Growing am höchsten und beim RECIST am geringsten war. Dennoch stimmten die ermittelten Responsekategorien beim Region …

The role of pulmonary arterial stiffness in right ventricular remodelling in COPD
… consistently better within-scan, interscan, intraobserver and interobserver reproducibility. Exercise did not result in a change in PWV (mean (95% CI) of the differences: 0.10 (−0.5 to 0.9), p=0.49) despite a significant rise in heart rate (65±2 to 87±3, p<0.0001), blood pressure (113/68 to …
