Transpulmonary passage of macroaggregates of albumin with exercise. Anterior (Ant) and posterior (Post) planar whole body images obtained following injections with technetium-99m macroaggregates of albumin at rest and during maximal treadmill exercise. The increased number of counts in the exercising muscles (legs) indicates intrapulmonary shunting of technetium-99m macroaggregates of albumin that have become trapped in systemic capillaries. The percent shunt in this individual at rest was 0.7%, which increased to 3.0% at maximal exercise. Color bar represents increasing count intensities with lighter colors.
