Enlargement of the cardiac silhouette on a frontal (or PA) chest x-ray can be due to a number of causes 1: cardiomegaly (most common cause by far) pericardial effusion. anterior mediastinal mass. prominent epicardial fat pad. expiratory radiograph.The cardiomediastinal Silhouette is a term used to describe the overall shape and size of the heart and its surrounding structures, as seen on an X-ray or other imaging test. An unremarkable cardiomediastinal Silhouette is one that appears normal in shape and size, without any abnormalities present.Air bronchogram refers to the phenomenon of air-filled bronchi (dark) being made visible by the opacification of surrounding alveoli (grey/white). It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli. Air bronchograms will not be visible if the bronchi themselves are opacified (e.g. …A widened mediastinum is a feature often seen on a plain chest x-ray. When the mediastinum is greater than 6 to 8cm, depending on which source, it is noted to be wide. A wide mediastinum has many causes which include the following: Thoracic aortic aneurysm of the ascending and proximal descending aorta. Aortic dissection of ascending and ...The cardiothoracic ratio is measured on a PA chest x-ray, and is the ratio of maximal horizontal cardiac diameter to maximal horizontal thoracic diameter (inner edge of ribs/edge of pleura).

The coronary arteries are the arteries that carry blood to the muscle layer of the heart.Jun 4, 2019 · Cardiomegaly means enlargement of the heart. The definition is when the transverse diameter of the cardiac silhouette is greater than or equal to 50% of the transverse diameter of the chest ...
Normal mediastinal contours. Here are some of the normal mediastinal contours often seen on chest X-rays. These contours are created by difference in density of anatomical structures of the mediastinum and adjacent tissues. Not all of these contours are present on all normal chest X-rays and their visibility depends on technical factors.Gross anatomy. Pericardial fluid can pool in these recesses and can be categorized by whether they arise from the transverse sinus, the oblique sinus, or the pericardial cavity proper 3: aortic recesses: arise from the transverse sinus. superior aortic recess. inferior aortic recess. pulmonic recesses: arise from the transverse sinus.The double-density sign, also known as the double right heart border , is seen on frontal chest radiographs in the presence of left atrial enlargement, and occurs when the right side of the left atrium extends behind the right cardiac shadow, indenting the adjacent lung and forming its own distinct silhouette 1-3 . If large enough, the left ...
