Respiratory gating in magnetic resonance imaging at 0. 5 Tesla
Journal Article
·
· Radiology; (United States)
A device for gating the acquisition of magnetic resonance images with chest wall motion was developed and the effects of respiratory gating upon image quality were studied. Images of respiratory gated examinations were compared with those of ungated examinations in 16 subjects. Respiratory gating removed gross motion artifacts from magnetic resonance images of the chest and abdomen. Resolution of small normal tissue structures, such as the portal and hepatic veins, is improved. In cardiac studies, respiratory gating improved the visualization and definition of the atria and ventricles.
