Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.

A pericardial cyst is an uncommon benign dilatation of the pericardial sac surrounding the heart. It can lead to symptoms by compressing nearby structures, but is usually asymptomatic. [ 1 ] Pericardial cysts can be congenital or acquired, and they are typically diagnosed with radiologic imaging.
A fat pad sign is an elevation of the anterior and posterior fat pads of the elbow joint, and suggests the presence of an occult fracture. Buccal fat pad can be seen in nursing babies. [1] The fat pad of the labia majora, which can be used as a graft, often as a so-called "Martius labial fat pad graft", which can be used, for example, in ...
Most pericardial effusions appear as an anechoic area (black or without an echo) between the visceral and the parietal membrane. [1] Complex or malignant effusions are more heterogeneous in appearance, meaning they may have variations in echo on ultrasound. [5] TTE can also differentiate pericardial effusion based on the size.
Pericardiocentesis should be performed with ultrasound guidance whenever possible to prevent complications. [2] [6] This allows practitioners to assess the location of the pericardial effusion and identify adjacent structures. [6] With ultrasound guidance, an apical approach is most often used, but parasternal and subxiphoid approaches can also ...
The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the ...
The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).
