A ventilation/perfusion lung scan, also called a V/Q lung scan, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, in order to determine the ventilation/perfusion ratio. The ventilation part of the test looks at the ability of air to reach all parts of the lungs, while the perfusion part evaluates how well blood circulates within the lungs. As Q in physiology is the letter used to describe bloodflow the term

Mismatch in ventilation/perfusion images is found in congenital heart and great vessel diseases [9–11], with a mismatched segmental Stress myocardial perfusion imaging is a nuclear cardiology procedure that is widely used to assess patients with known or suspected coronary artery disease. A cardiac perfusion scan measures the amount of blood in your heart muscle at rest and after it has been stressed. It is often done to find out what may be causing The myocardial perfusion scan looks at how well your heart is pumping and the flow of blood to your heart muscle. Your doctors may refer you for other tests if they Myocardial perfusion is an imaging test.

Background: Patients with complete left bundle branch block (LBBB) often show a false-positive ischaemic pattern in the interventricular septum on thallium-201 (201TI) stress-rest myocardial perfusion scintigraphy.

The objectives of this article are to review different patterns and potential pitfalls of quantitative lung perfusion scintigraphy (LPS) in patients with congenital heart disease (CHD). The patterns of quantitative LPS in patients with CHD include normal symmetrical bilateral perfusion to both lungs …

Each, in principal conical, bronchopulmonary segment is supplied by a single artery. This test is called the “Myocardial scintigraphy perfusion imaging at exercice”, “MIBI at exercice” or “MIBI with a treadmill”. An oxygen detective in the heart muscle The exam takes place with a radioactive tracer present in the body, allowing the oxygen to be “seen” in the cardiac muscle.
