Assessment of myocardial perfusion during pharmacologic contrast stress echocardiography

This study is the first to demonstrate the lack of serious or unexpected size effects using Optison, dipyridamole, and thallium-201 through the same intravenous line during a pharmacologic stress test. Intermittent 1:4 triggering using single-mode poweer contrast imaging correlated well with thalliu...

Description
Summary:This study is the first to demonstrate the lack of serious or unexpected size effects using Optison, dipyridamole, and thallium-201 through the same intravenous line during a pharmacologic stress test. Intermittent 1:4 triggering using single-mode poweer contrast imaging correlated well with thallium-201 single-photon emission computed tomography for detecting perfusion defects in subjects with known or suspected coronary artery disease, and this concordance durther improved when wall motion analysis was addedto myocardial contrast echocardiography.
