  2. CT pulmonary angiogram - Wikipedia

    en.wikipedia.org/wiki/CT_pulmonary_angiogram

    CTPA was introduced in the 1990s as an alternative to ventilation/perfusion scanning (V/Q scan), which relies on radionuclide imaging of the blood vessels of the lung. It is regarded as a highly sensitive and specific test for pulmonary embolism. [1] CTPA is typically only requested if pulmonary embolism is suspected clinically.

  3. Pulmonary artery - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_artery

    The pulmonary artery pressure (PA pressure) is a measure of the blood pressure found in the main pulmonary artery. This is measured by inserting a catheter into the main pulmonary artery. [ 13 ] : 190–191 The mean pressure is typically 9–18 mmHg, [ 14 ] and the wedge pressure measured in the left atrium may be 6–12 mmHg.

  4. Pulmonary angiography - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_angiography

    Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.

  5. Computed tomography angiography - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography...

    CT angiography should not be used to evaluate for pulmonary embolism when other tests indicate that there is a low probability of a person having this condition. [5] A D-dimer assay might be a preferred alternative to test for pulmonary embolism, and that test and a low clinical prediction score on the Wells test or Geneva score can exclude ...

  6. Digital subtraction angiography - Wikipedia

    en.wikipedia.org/wiki/Digital_subtraction...

    Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...

  7. Angiography - Wikipedia

    en.wikipedia.org/wiki/Angiography

    Pulmonary angiography is used to visualise the anatomy of pulmonary vessels. Pulmonary angiography may be used during embolization of pulmonary arteriovenous malformations. [10] In addition, pulmonary angiography may be performed during treatment of pulmonary embolisms. [11]

  8. Pulmonary bay - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_bay

    Pulmonary bay is a medical term which describes a finding on the chest radiograph. In pulmonary bay, there is a concavity where you would normally find the pulmonary artery . Pulmonary bay is most commonly associated with tetralogy of Fallot , however it may also be seen in other conditions where there is a reduced outflow from the pulmonary ...

  9. Chang sign - Wikipedia

    en.wikipedia.org/wiki/Chang_sign

    It refers to the dilatation and abrupt change in calibre of a previously normal descending pulmonary artery on a chest X-ray film. [1] Chang sign usually appears within 24 hours of the onset of chest pain due to pulmonary embolism, [ 2 ] and the maximal dilatation of the descending pulmonary artery often occurs in two to three days after the ...
