Angiography is an imaging test that uses x-rays and a special dye to see the insides of the arteries.

You will be asked to lie on an x-ray table.Before the test starts, you will be given a mild sedative to help you relax. An area of your body, most often the arm or groin, is cleaned and numbed with a local numbing medicine (anesthetic). The radiologist inserts a needle or makes a small cut in a vein in the area that has been cleaned. A thin hollow tube called a catheter is inserted. The catheter is placed through the vein and carefully moved up into and through the right-sided heart chambers and into the pulmonary artery, which leads to the lungs. The doctor can see live x-ray images of the area on a TV-like monitor, and use them as a guide. Once the catheter is in place, dye is injected into the catheter. X-ray images are taken to see how the dye moves through the lungs' arteries. The dye helps detect any blockages to blood flow.Your pulse, blood pressure, and breathing are checked during the procedure. Electrocardiogram (ECG) leads are taped to your arms and legs to monitor your heart.PulseThe pulse is the number of heartbeats per minute.ImageRead Article Now Book Mark Article ElectrocardiogramAn electrocardiogram (ECG) is a test that records the electrical activity of the heart.ImageRead Article Now Book Mark Article After the x-rays are taken, the needle and catheter are removed.Pressure is applied to the puncture site for 20 to 45 minutes to stop the bleeding. After that time, the area is checked and a tight bandage is applied. You should keep your leg straight for 6 hours after the procedure.Rarely, medicines are delivered to the lungs if a blood clot has been found during the procedure. How to Prepare for the Test You may be asked not to eat or drink anything for 6 to 8 hours before the test.You will be asked to wear a hospital gown and sign a consent form for the procedure. Remove jewelry from the area being imaged.Tell your health care provider:If you are pregnant If you have ever had any allergic reactions to x-ray contrast material, shellfish, or iodine substances If you are allergic to any medicines Which medicines you are taking (including any herbal preparations) If you have ever had any bleeding problems How the Test will Feel The x-ray table may feel cold. Ask for a blanket or pillow if you are uncomfortable. You may feel a brief sting when the numbing medicine is given and a brief, sharp, stick as the catheter is inserted.You may feel some pressure as the catheter moves up into the lungs. The contrast dye can cause a feeling of warmth and flushing. This is normal and usually goes away in a few seconds.You may have some tenderness and bruising at the site of the injection after the test. Why the Test is Performed The test is most often used to detect blood clots (pulmonary embolism) and other blockages in the blood flow in the lung. Most of the time, your provider will have tried other tests to diagnose a blood clot in the lungs.Blood clotsBlood clots are clumps that occur when blood hardens from a liquid to a solid.

Your provider will monitor and regulate the x-rays to provide the least amount of radiation exposure. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks for x-rays. Considerations Computed tomography (CT) angiography of the chest has largely replaced this test.
