Description
Summary:A simple technique is described for generating ventilation/ perfusion ratio and perfusion/ventilation ratio images from the posterior Tc-99m PYP aerosol inhalation and Tc-99m MAA perfusion images obtained during routine lung scintigraphy. These images highlight areas of ventilation/perfusion incongruence—mismatch or reverse mismatch—that may sometimes be difficult to detect on conventional images.
