Generation Of Parametric Images During Routine Tc-99m Pyp Inhalation/Tc-99m Maa Perfusion Lung Scintigraphy - Technical Note
CLINICAL NUCLEAR MEDICINE(1991)
Abstract
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.
