2018年2月26日 · A pulmonary ventilation/perfusion scan measures how well air and blood are able to flow through your lungs.

2023年1月19日 · A VQ scan is a two-part test that providers use to diagnose a pulmonary embolism. It measures the airflow (ventilation) and blood flow (perfusion) in 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.

A pulmonary ventilation/perfusion scan involves two nuclear scan tests to measure breathing (ventilation) and circulation (perfusion) in all areas of the lungs. Radioactive albumin injection is part of a nuclear scan test that is performed to measure the supply of blood through the lungs.

2024年6月14日 · V/Q (ventilation/perfusion) scan is a scintigraphic examination of the lung that evaluates pulmonary vasculature perfusion and segmental bronchoalveolar tree ventilation. A chest x-ray should be performed within 12 to 24 hours and reviewed prior to lung scintigraphy 2 as there are other causes of perfusion defects such as atelectasis.

2023年5月22日 · 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.

2021年10月22日 · Ventilation-perfusion (V/Q) scintigraphy is the oldest noninvasive radiologic examination available for evaluating pulmonary embolism (PE); its initial use in humans for this purpose was reported in 1964 by Quinn et al (1). It was not …

A lung ventilation perfusion scan is a nuclear medicine test that provides images of the lungs to evaluate their function. This non-invasive procedure involves two main components: a ventilation study and a perfusion study.

Both components of the Lung Ventilation/perfusion Scan are crucial for diagnosing conditions that affect breathing and circulation within the lungs. The results from this scan can guide treatment plans and further investigations, making it an invaluable tool in respiratory medicine.
