The black areas on either side are the lungs, with around it the chest wall. A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [1] It is a preferred choice of imaging in the diagnosis of ...
Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism). [ 6 ] Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. [ 1 ] Symptoms of a blood clot in the leg may also be present, such ...
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography —the visualization of arteries and veins —throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of ...
Chronic thromboembolic pulmonary hypertension. Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads ...
Bronchial artery embolization. Specialty. Pulmonology, interventional radiology. [edit on Wikidata] Bronchial artery embolization is a treatment for hemoptysis, abbreviated as BAE. It is a kind of catheter intervention to control hemoptysis (airway bleeding) by embolizing the bronchial artery, which is a bleeding source.
Signs and symptoms. The symptoms of fat embolism syndrome (FES) can start from 12 hours to 3 days after diagnosis of the underlying clinical disease. The three most characteristic features are: respiratory distress, neurological features, and skin petechiae. [5] Respiratory distress (present in 75% of the cases) can vary from mild distress ...
Pulmonology, cardiology. Lung infarction or pulmonary infarction occurs when an artery to the lung becomes blocked and part of the lung dies. [1] It is most often caused by a pulmonary embolism. Because of the dual blood supply to the lungs from both the bronchial circulation and the pulmonary circulation, this tissue is more resistant to ...
A CT pulmonary angiogram, in this case showing pulmonary embolism of saddle-type, which becomes more radiolucent than the radiocontrast filled blood surrounding it (but it may be indistinguishable without radiocontrast). Contrast CT, or contrast-enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast.
