A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
Causes of Kerley B lines include pulmonary edema, lymphangitis carcinomatosa and malignant lymphoma, viral and mycoplasmal pneumonia, interstitial pulmonary fibrosis, pneumoconiosis, and sarcoidosis. They can be an evanescent sign on the chest x-ray of a patient in and out of heart failure.
Azygos lobe on chest X-ray. Arrowheads show the delineation of the lobe. Arrow points to the azygos vein. In human anatomy, an azygos lobe is a normal anatomical variation of the upper lobe of the right lung. [1] It is seen in 0.3% of the population. [2]
A) Normal chest radiograph; B) Q fever pneumonia affecting the right lower and middle lobes. Note the loss of the normal radiographic silhouette (contour) between the affected lung and its right heart border as well as between the affected lung and its right diaphragm border. This phenomenon is called the silhouette sign: Differential diagnosis
This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura.
While the chest x-ray is normal in the majority of PE cases, [2] the Westermark sign is seen in 2% of patients. [3] Essentially, this is a plain X-ray version of a filling defect as seen on computed tomography pulmonary arteriogram. The sign results from a combination of: the dilation of the pulmonary arteries proximal to the embolus and
Tuberculosis creates cavities visible in x-rays like this one in the patient's right upper lobe.. A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary.
