Lateral supine lung perfusion imaging

Quantitative analysis of lateral supine pulmonary perfusion imaging is a method to evaluate pulmonary artery pressure. The role of lateral supine pulmonary perfusion imaging is to evaluate pulmonary arterial pressure. Abnormal results: Myocardial perfusion imaging shows that myocardial cells have selective uptake of certain radionuclides or labeled compounds. The amount of uptake is directly proportional to myocardial blood flow perfusion. The coronary lumen is narrowed to a certain extent (more than 50%), and the local myocardial blood flow is reduced. Therefore, the tracer uptake at this site is reduced, and the radiation distribution is sparse or defective.
