Methods of contrast administration for myocardial perfusion imaging: Continuous infusion versus bolus injection

The debate over the optimal contrast administration method involves many issues. This article discusses bolus versus infusion administration pertaining to myocardial perfusion imaging. Continuous infusion ensures efficient and optimal data capture during contrast studies and is preferred over bolus injection for both theoretical and practical reasons. Although bolus administration is easier, its relative disadvantages outweigh its usefulness in myocardial perfusion imaging. (C) 2002 by Excerpta Medica, Inc.
