A new study, which looked at pneumonia cases that developed during the 2009 H1N1 influenza pandemic, suggests that this screening tool may not always be accurate enough, especially in detecting the early interstitial stage. Pneumonia is an infection of the lung that can be caused by bacteria, viruses, and fungi. Some pneumonias are difficult or impossible to see on X-ray.

These findings are consistent with practical clinical experience. If present, however, they only confirm the presence of collapse and do not give any further information as to the precise location of the collapse within that lung, or the underlying aetiology: Collapse of each lobe individually gives rise to particular distinct patterns which can be recognised on a chest X-ray. Google Scholar, Welte T, Torres A, Nathwani D. Clinical and economic burden of community-acquired pneumonia among adults in Europe. The collateral pores of Kohn allow air drift between adjacent alveoli. . However, it has been suggested by some that in the community, milder cases of infection treated as outpatients could be diagnosed on clinical grounds alone without the performance of chest imaging [12]. information and will only use or disclose that information as set forth in our notice of Lobar collapse can be caused by a number of entities as detailed in the diagram below: Once the airway is completely occluded, trapped air distal to the obstruction is absorbed into the surrounding tissues collapsing the alveoli as it does so.

Junior Doctors Interpretation of CXRs is More Consistent than Consultants in the Context of Possible Pneumonia. It is a pretty routine examination for somebody with symptoms. For many of these reasons it is the authors belief that a chest radiograph should be performed in patients for suspected CAP, if at all possible. Clearly much of this inconsistency will be centred on certain chest radiographs which are particularly difficult to interpret, but in those cases, if the decision to diagnose pneumonia was based on the chest radiograph alone, we could save some time and money by flipping a coin. The combination of their individual silhouettes adds up to become a bird, a rabbit, a dog and all manner of other possibilities. One study investigated the criteria used by primary care physicians to diagnose pneumonia, as opposed to acute bronchitis or upper respiratory tract infections, in the outpatient setting [18].

Some pneumonias can not be seen on X-ray or are very subtle. Chest X-rays (CXRs) can help triage for Coronavirus disease (COVID-19) patients in resource-constrained environments, and a computer-aided detection system (CAD) that can identify pneumonia on CXR may help the triage of patients in those environment where expert radiologists are not available. Since the aerated lower lobe is still sitting on the diaphragm, the diaphragm will still be seen very clearly although the left heart border may be obscured: Collapse of the left lower lobe can give rise to a double left heart border where the triangularly shaped opacity of the collapsed left lower lobe sits behind the heart and creates a second edge next to the edge of the heart.

Bronchopneumonia appears on a chest X-ray as bilateral patchy shadows and typically predominates at the lung bases: Lobar pneumonias have specific appearances, which can be explained by the anatomical relationships of the lobes of the lung to their surrounding structures. The largest published study of inter-observer agreement in the interpretation of chest radiograph in the context of possible pneumonia revealed radiologists had kappa = 0.38 [23]. 1. https://doi.org/www.dx.doi.org/10.1016/j.rmed.2005.06.018, Bewick T, Greenwood S, Wei SL.
