Dedicated<unk> y room Conditions commonly identified by<unk> y * Pneumonia * Pneumothorax * Interstitial lung disease * Heart failure * Bone fracture * Hiatal hernia<unk> s are used to diagnose many conditions involving the<unk>  wall, including its bones, and also structures contained within the thoracic cavity including the lungs, heart, and great vessels. Pneumonia and congestive heart failure are very commonly diagnosed by<unk> .<unk> s are also used to screen for job-related lung disease in industries such as mining where workers are exposed to dust. For some conditions of the<unk> y is good for screening but poor for diagnosis. When a condition is suspected based on<unk> y, additional imaging of the<unk>  can be obtained to definitively diagnose the condition or to provide evidence in favor of the diagnosis suggested by initial<unk> y. Unless a fractured rib is suspected of being displaced, and therefore likely to cause damage to the lungs and other tissue structures, x-ray of the<unk>  is not necessary as it will not alter patient management. The main regions where a<unk>  X-ray may identify problems may be summarized as ABCDEF by their first letters: *Airways, including hilar adenopathy or enlargement *Breast shadows *Bones, e.g. rib fractures and lytic bone lesions *Cardiac silhouette, detecting cardiac enlargement *Costophrenic angles, including pleural effusions *Diaphragm, e.g. evidence of free air, indicative of perforation of an abdominal viscus *Edges, e.g. apices for fibrosis, pneumothorax, pleural thickening or plaques *Extrathoracic tissues *Fields (lung parenchyma), being evidence of alveolar flooding *Failure, e.g. alveolar air space disease with prominent vascularity with or without pleural effusions
