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.
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
Chest X-ray: X-ray images help to visualize the condition of the lungs and heart. If the heart is enlarged on an X-ray, other tests will usually be needed to find the cause. A useful measurement on X-ray is the cardio-thoracic ratio, which is the transverse diameter of the heart, compared with that of the thoracic cage. [24]
A chest X-ray, computed tomography (CT) scan, or ultrasound is usually used to confirm its presence. [5] Other conditions that can result in similar symptoms include a hemothorax (buildup of blood in the pleural space), pulmonary embolism, and heart attack. [2] [11] A large bulla may look similar on a chest X-ray. [3]
A chest X-ray is usually performed on people with fever and, especially, hemoptysis (blood in the sputum), to rule out pneumonia and get information on the severity of the exacerbation. Hemoptysis may also indicate other, potentially fatal, medical conditions. [5]
Chest X-ray has been used for many years to diagnose pulmonary edema due to its wide availability and relatively cheap cost. [4] A chest X-ray will show fluid in the alveolar walls, Kerley B lines , increased vascular shadowing in a classical batwing peri- hilum pattern, upper lobe diversion (biased blood flow to the superior parts instead of ...
Chest x-ray screenings were found to detect 6 times as many new cancers as sputum tests, proving the disutility of sputum tests in lung cancer screening. [17] However, the results from the Mayo Lung Project and the Hopkins and Memorial Sloan-Kettering studies were eventually discredited, due to failure to account for lead time and length time ...
Pneumonia as seen on chest x-ray. A: Normal chest x-ray.B: Abnormal chest x-ray with shadowing from pneumonia in the right lung (left side of image).. Hospital-acquired pneumonia (HAP) or nosocomial pneumonia refers to any pneumonia contracted by a patient in a hospital at least 48–72 hours after being admitted.
