Flank pain has been reported with ultrasound (US) contrast agents. The purpose of this study is to determine whether there is retention of ultrasound contrast agents in the renal microcirculation, which has been described in mice.
In this study patients undergoing clinically indicated contrast echocardiography will have renal ultrasound performed 10 minutes after completion of contrast infusion to determine the presence and location of renal retention of lipid microbubbles.
