eFAST (extended focused assessment with sonography for trauma) allows an emergency physician or a surgeon the ability to determine whether a patient has pneumothorax, hemothorax, pleural effusion, mass/tumor, or a lodged foreign body. The exam allows for visualization of the echogenic tissue, ribs, and lung tissue.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Percussion is performed in a systematic matter, from the upper chest to the lower ribs, and resonance is compared between the left and right sides of the chest. This is done from the front and back of the thorax. [14] Percussion over different body tissues results in five common "notes". [14] Resonance: Loud and low pitched. Normal lung sound. [15]
Many emergency physicians now view screening ultrasound as a tool, and not a procedure or study. It is primarily used to quickly and correctly ascertain a limited set of internal injuries, specifically those injuries where conventional methods of determining them, such as trauma to the torso or heart, would either take too long, require too much time to prepare, or introduce greater risk to ...
These radioactive compounds are administered so that specific tissues take them up. The amount and anatomical detail of the uptake produces the scan result. SPECT scan: video link: Interventional radiology: minimally invasive surgeries under radiological imaging, e.g. angioplasty, TIPS. Brachytherapy apparatus: video link: Lead shielding
The left paratracheal stripe is more variable and only seen in 25% of normal patients on posteroanterior views. [ 7 ] Localization of lesions or inflammatory and infectious processes can be difficult to discern on chest radiograph, but can be inferred by silhouetting and the hilum overlay sign with adjacent structures.
In medicine, Imaging Lung Sound Behavior with Vibration Response Imaging (VRI) is a novelty computer-based technology that takes the concept of the stethoscope to a more progressive level. Since the invention of the stethoscope by René-Théophile-Hyacinthe Laennec France in 1816 , physicians have been utilizing lung sounds to diagnose various ...
Ovarian vein embolization is a same-day treatment which takes place in an interventional radiology suite. The interventional radiologist gains access through a large vein in the groin, called the femoral vein , by using a small catheter , which is a flexible tube like a strand of spaghetti.
