What is a VQ scan used for? Providers most often use a VQ scan to diagnose a blood clot in your lungs (pulmonary embolism, or PE). A pulmonary embolism can be fatal if left untreated. It’s also used to diagnose chronic thromboembolic pulmonary hypertension (CTEPH), a cause of high blood pressure in the blood vessels in your lungs.

2018年2月26日 · What Is a VQ Scan? A pulmonary ventilation/perfusion (or VQ) scan is a series of two lung scans. The scans are either performed together or one after the other, but are often referred to as one...

A VQ scan is short for Lung or Pulmonary Ventilation (V) and Perfusion (Q) Scans. It’s an imaging test that measures air and blood flow in your lungs. Your doctor may request...

What is a V/Q scan? A V/Q scan consists of two imaging tests that look for certain lung problems. The tests are: The two scans may be done separately or together. A V/Q scan uses a small amount of a radioactive substance called a tracer. The tracer can help your health care provider see how well air and blood flow through your lungs.

2023年1月13日 · Pulmonary ventilation (V) and Perfusion (Q) scan, also known as lung V/Q scan, is a nuclear test that uses the perfusion scan to delineate the blood flow distribution and the ventilation scan to measure airflow distribution in the lungs.

A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1][2] in order to determine the ventilation/perfusion ratio.

2023年3月24日 · The ventilation-perfusion scan is a nuclear scan so named because it studies both airflow (ventilation) and blood flow (perfusion) in the lungs. The initials V-Q are used in mathematical equations that calculate airflow and blood flow.

A ventilation-perfusion (VQ) scan measures airflow (ventilation) and tracks blood flow (perfusion) in the lungs. A VQ lung scan is considered a single procedure, but involves two separate scans. Both use a very restricted amount of radioactive material to capture images of the lungs.

2025年2月9日 · A VQ scan is a test used to show the air flow and blood flow in your lungs. It is usually done if your healthcare provider thinks you have a pulmonary embolism (blood clot). A pulmonary embolism (PE) may be caused by a blood clot that travels from your leg to your lungs.

What is a VQ scan? A ventilation/perfusion (VQ) scan is a test that checks to see if your lungs are getting enough air and blood flow to them. The VQ is a two part test. The first part, called ventilation, looks to see if air is getting to each area of your lungs.
