Myocardial Perfusion Imaging Using Ultrasound Contrast Agents

Contrast echocardiography for myocardial perfusion imaging using intravenous agents: progress and promises.

AIMS This article is a convenient overview to assist the interested echocardiographist towards acquiring his own experience in the field of myocardial perfusion imaging using intravenous contrast agents. This goal is now pursued in many centres, since contrast echo holds the advantages of cardiac ultrasound (non-invasiveness, high spatial and temporal resolution, wide availability, use of non-i...

Molecular ultrasound imaging using microbubble contrast agents Paul

Radiopharmaceutical agents for myocardial perfusion imaging.

Myocardial perfusion imaging (MPI) is a wellestablished noninvasive method of assessing coronary blood flow.1–5 MPI is capable of identifying regional abnormalities in coronary artery blood flow and determining their physiological relevance to myocardial function and viability. MPI requires the intravenous injection of a radioactive blood flow marker followed by imaging of regional myocardial u...

High Framerate Imaging of Ultrasound Contrast Agents

Phospholipid-coated ultrasound contrast agents may deflate or even collapse because of stress resulting from ultrasound-induced oscillations. In this work we investigate the behavior of isolated contrast agent microbubbles during prolonged ultrasound excitation. Isolated microbubbles placed in a thin capillary tube were excited with hundreds of ultrasound pulses at a low mechanical index, and t...

Quantifying myocardial perfusion using contrast echocardiography.

There is a complex relation between what can be seen using perfusion imaging techniques, and what can be measured.
