Pulmonary angiography
Pulmonary Angiography
Pulmonary angiography (pronounced: pul-mon-ary an-gee-og-raphy) is a medical imaging procedure used to visualize the pulmonary arteries in the lungs.
Etymology
The term "pulmonary angiography" is derived from three Greek words: "pulmo" meaning lung, "angeion" meaning vessel, and "graphein" meaning to write or record.
Procedure
Pulmonary angiography involves the injection of a contrast agent into the blood vessel to make the pulmonary arteries visible on an X-ray. The procedure is typically performed to diagnose or evaluate certain conditions such as pulmonary embolism or pulmonary hypertension.
Risks and Complications
Like any medical procedure, pulmonary angiography carries some risks. These may include allergic reactions to the contrast agent, bleeding or infection at the injection site, and damage to the blood vessels. In rare cases, the procedure can cause kidney damage or a serious allergic reaction.
