[1] While contrast agents have not been a critical part of image acquisition in echocardiography, image quality may be suboptimal, particularly in obese patients, in critically ill, ventilated ...

Contrast echocardiography is a specialized imaging technique that enhances the quality of ultrasound images, particularly in assessing heart function and structure. This technique utilizes ...

"Echo is biologically very safe. It uses no contrast medium, no radiation-- so it can be repeated often. And echo can evaluate the function of the heart muscle and valves better than any modality." ...

This results in decreased flow velocities and rouleaux formation of red blood cells, which is seen as “spontaneous echo contrast” on echocardiography. If a thrombus in the left atrial ...
