“…Pathophysiology The pathophysiological changes within the interstitial tissues necessary to generate diffuse BLA with ultrasound have been identified by CT studies as abnormalities of the secondary pulmonary lobule including: thickening of the interlobular septa, areas of ground-glass opacity, and diffuse alveolar opacities [18,19]. These abnormalities are seen in a variety of interstitial lung conditions, characterized by the presence of interstitial fluid, cellular infiltration and fibrosis.…”

IntroductionIn years gone by examination of patients with pulmonary disorders rested essentially on a clinician's bedside physical examination, of auscultation and percussion, complimented with blood gas analysis and X-ray imaging. Lung ultrasound has emerged into this context as a real-time bedside procedure, delivering information relevant to the clinician's differential diagnosis. A large part of sonographic lung examination involves the interpretation of artefacts, thus knowledge of the origin of typical artefacts is important. Although indirect sonographic signs, nonetheless reliable conclusions on the condition of the lung can be inferred. Particularly the of quantity and distribution of B-lines can establish important assessment of the cause and degree of fluid load within the interstitium.All focused ultrasound investigations, including bedside lung ultrasound, allow symptom evaluation considering multiple organ-systems yet with minimal time delay. Such integration of imaging with clinical assessment and treatment is called Point-of-Care Ultrasound (POCUS) and should be understood as an extension of the physical examination. POCUS offers a unique but crucial role, integrating clinical and other imaging findings, including cardiac ultrasound (echocardiography), chest radiography, and computed tomography (CT) scans is crucial, which alone may lack the required accuracy.The emergence of differences in approach to lung sonography, technique and nomenclature, provided the AbstractThe science of lung ultrasound has grown tremendously over the last two decades and lung ultrasound has not only entered the mainstream of point of care ultrasound but has become a dominant topic. Understanding lung ultrasound signs and artifacts is critical to being able to correlate findings with actual pathology and normal anatomy and physiology. Investigators have described multiple lung ultrasound artifacts and findings and it is important to understand both the physics and anatomic basis behind them. Additionally, ultrasound machine use and transducer selection can significantly affect results obtained on patient during an examination and the provider must carefully choose the correct settings. This manuscript describes the state of the art in ultrasound artifact recognition and correlation as well as management of ultrasound technology to optimize diagnostic success.Keywords: ultrasound, lung, artifacts, pathology, guidelines [2,[11][12][13][14][15] we discuss the prominent role of the particular artefacts of lung sonography answering differential-diagnostic questions in patients with cardio-pulmonary diseases.

“…Furthermore, HRCT scans allow for small differences in tissue density to be detected and quantified. Due to the higher sensitivity of HRCT as compared to normal CT and chest radiograph (Aberle et al 1988a, b;Akira et al 1990Akira et al , 1991Bessis et al 1992;Friedman et al 1988), inter-observer variability for the detection of radiological signs of early asbestosis and of pleural fibrosis (plaques, calcifications) was expected to be lower for HRCT than for chest radiography-especially if a standardized HRCT classification questionnaire similar to the ILO classification (Welch et al 1998) is used. The present study focuses on the comparative interpretation and inter-reader variability of radiographs and HRCT scans of a cohort of formerly asbestos-exposed employees whilst using the ILO classification sheets for radiographs and a newly created standardized CT classification sheet which was based on the ILO classification sheet of radiographs.…”

High resolution computed tomography scans are superior to X-rays in detecting lung alterations after asbestos exposure and are supposedly easier to interpret. Nevertheless, inter-observer variability did not differ between the two methods in this study. This was probably due to the only discrete asbestos-related lung or pleura alterations of this cohort and to the unfamiliar CT classification sheet, which was revised on the basis of the presented results.

Effects of contrast material on computed tomographic measurements of lung volumes in patients with acute lung injury

BackgroundIntravenous injection of contrast material is routinely performed in order to differentiate nonaerated lung parenchyma from pleural effusion in critically ill patients undergoing thoracic computed tomography (CT). The aim of the present study was to evaluate the effects of contrast material on CT measurement of lung volumes in 14 patients with acute lung injury.MethodA spiral thoracic CT scan, consisting of contiguous axial sections of 10 mm thickness, was performed from the apex to the diaphragm at end-expiration both before and 30 s (group 1; n = 7) or 15 min (group 2; n = 7) after injection of 80 ml contrast material. Volumes of gas and tissue, and volumic distribution of CT attenuations were measured before and after injection using specially designed software (Lungview®; Institut National des Télécommunications, Evry, France). The maximal artifactual increase in lung tissue resulting from a hypothetical leakage within the lung of the 80 ml contrast material was calculated.ResultsInjection of contrast material significantly increased the apparent volume of lung tissue by 83 ± 57 ml in group 1 and 102 ± 80 ml in group 2, whereas the corresponding maximal artifactual increases in lung tissue were 42 ± 52 ml and 31 ± 18 ml.ConclusionBecause systematic injection of contrast material increases the amount of extravascular lung water in patients with acute lung injury, it seems prudent to avoid this procedure in critically ill patients undergoing a thoracic CT scan and to reserve its use for specific indications.
