Jan 19, 2023 · A VQ scan is a two-part test that providers most commonly use to diagnose a blood clot in your lungs (pulmonary embolism). It measures the airflow (ventilation) and blood flow (perfusion) in your lungs.

Feb 26, 2018 · 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 …

Mar 25, 2025 · V/Q (ventilation/perfusion) scan is a scintigraphic examination of the lung that evaluates pulmonary vasculature perfusion and segmental bronchoalveolar tree ventilation.

May 18, 2015 · 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 V/Q scan consists of two imaging tests that measure the air and blood flow in your lungs. It's most often used to check for a blood clot (pulmonary embolism).

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.

Aug 5, 2023 · 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...

May 22, 2023 · A ventilation-perfusion (VQ) scan is a diagnostic test using radioisotopes to evaluate lung perfusion and ventilation. Ventilation-perfusion scan consists of two portions, a ventilation (V) scintigraphy and a perfusion (Q) scintigraphy.

Mar 24, 2023 · 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 VQ (lung) scan looks at the air supply and blood supply to your lungs. It helps us to diagnose lung conditions. It is most commonly used to detect the presence of blood clots in the lungs (pulmonary embolism, PE).
