Pulmonary angiography is a test that studies blood flow in your lungs.
It is often used after other tests show signs of these problems.
This test can be done in more than one way.

Invasive pulmonary angiography usesX-raysandcontrast dyeto visualize the blood vessels.
It may be an appropriate option for children and pregnant people for whom radiation exposure is contraindicated.
The main advantage of PMRA is the unique combination of structural and functional imaging.
PMRA involves lying on your back while the table is rolled into the center of the MRI.
The procedure may be used with or without contrast dye.
It requires extended holding of your breath, which may be a problem for some people with respiratory problems.
The procedure can take 15 to 60 minutes, depending on the focus area and number of scans.
During the procedure, you will hear loud thumping noises.
Earplugs or headphones can help to reduce the effects of the noise.
Depending on the images needed, the scan can often be completed within a few minutes or less.
The scans produce detailed 2D images that a computer can combine to form three-dimensional (3D) images.
It involves injecting contrast dye into the groin or arm.
A pulmonary angiogram involves the insertion of a thincatheter(flexible tube) into your groin or arm.
A local anesthetic is used at the site of the insertion.
Contrast dye is injected into the catheter when it is properly placed.
Your heart is monitored byelectrocardiogram (ECG)leads in your arms and legs.
Normal results indicate normal structures for the age of the person being examined.
Always inform your healthcare provider if you experience any unusual sensations during or after a pulmonary angiogram.
A pulmonary embolism is the most common pathology of a pulmonary angiogram.
It can be performed using invasive or noninvasive techniques.
The gold standard is CT pulmonary angiography.
Pulmonary angiography can also be used to find other problems that can affect blood flow in the lungs.
Results can show problems such as narrowed blood vessels in the lungs or a pulmonary aneurysm.
