Abstract
A partial‐body plethysmograph was developed for measuring the respiratory flow of anesthetized mice during routine microimaging experiments performed in the close confines of an 89‐mm‐diameter, vertical‐bore magnet. Respiratory flow patterns were used for synchronizing conventional T2‐weighted spin‐echo imaging with the respiratory cycle, thereby, significantly reducing motion‐induced artifacts and increasing observed liver lesion contrast.
