Contrast-enhanced ultrasound imaging (CEUS) is a non-invasive imaging modality that utilizes air-filled microspheres as blood pool agents, which act as intravascular indicators, resulting in improved accuracy and reliability in performing ultrasound images of the heart. CEUS is increasingly used throughout the US, South America, Australia, the Middle East, Europe, Japan, Canada, and Asia as a…

Contrast echocardiography (CE) is 40 years old this year. Gamiak and Shah first described the use of ultrasound (US) contrast in 1968 during the early days of M-mode echocardiography.1 In that study, US contrast was produced by inadvertently introducing air bubbles in the indocyanine green solution that was injected into the left heart during cardiac catheterisation and observing its appearance…

Contemporary approved echo contrast agents share a common approved indication of left ventricular opacification and enhancement of endocardial border delineation for the assessment of left ventricular function in patients with technically suboptimal echocardiograms (ECGs). The use of echo contrast agents with advanced imaging technologies has resulted in the conversion of many non-diagnostic ECGs…

The cardiac imaging field has experienced significant improvements over the last decade due to technological advances. Cardiac computed tomography (CT), cardiac magnetic resonance imaging (MRI), nuclear cardiology, and echocardiography have all become feasible imaging modalities for physicians to evaluate in order to answer specific diagnostic questions. Each of the aforementioned modalities has…

Ultrasound contrast agents capable of transpulmonary passage following intravenous injection have been commercially available since the 1990s. These agents are microbubbles, which are smaller than red blood cells and persist long enough (due to reduced rate of gas diffusion) to reach the left ventricle (LV).1–3 Ultrasound contrast agent applications included LV cavity opacification, enhancement…

Tissue Doppler-based measurements of myocardial strain are possible and accurate for structures that move along the ultrasound beam, but are underestimated in other directions and even impossible for angles close to 90º. To overcome these limitations, the speckle tracking technique was introduced in 2004, offering a more user-friendly workflow and better reproducibility.1 This echocardiographic…

The use of iodinated contrast media (CM) for both diagnostic imaging and interventional studies continues to increase. The introduction of multi-detector computed tomography (MDCT) scanners allows for quicker imaging of internal organs, and image acquisition is now fast enough for study of the coronary arteries. This technology requires the delivery of a high concentration of iodine to the…
