Hace 5 días · This effect is called the “Spine Sign”. The spine sign may indicate anything from pneumonia, a lung mass, a mediastinal mass, pleural fluid or anything of sufficient density to attenuate more x-rays passing through the lower thoracic spine than normally. It may be particularly useful in diagnosing left lower lobe pneumonia which falls below ...
Hace 5 días · Pathology. The extent and pattern of soft tissue and osseous facial injuries vary according to the energy of impact. Isolated fracture is most common with lower energy trauma, whereas high energy blunt and penetrating trauma results in a more complex, less predictable injury pattern.
Hace 4 días · In this study, we examine the Sb isotopic fractionation induced by adsorption on β-MnO 2 in different experiments (kinetic, isothermal, effect of pH). We observe that adsorption on β-MnO 2 surfaces preferentially enriches lighter Sb isotopes through equilibrium fractionation, with Δ 123 Sb aqueous-adsorbed of 0.55–0.79 ‰.
Hace 12 horas · In this study, the magnitude of the X-ray radiation energy remained constant for the different scan durations, indicating that longer and shorter scans are at a constant radiation intensity. It appears that if the intensity is sufficient, the exposure time is not an issue for the lengths of exposures investigated and does not change the accuracy of this measurement.
Area of Interest included. Images can only be of diagnostic quality if all the anatomical areas are included on the mobile X-ray image. These are: Superiorly the supraclavicular region defined by the superior margin of the 1st rib bilaterally. Lateral margins of the chest. The hemidiaphragms.
