A bubble echocardiogram is an extension of this that uses simple air bubbles as a contrast medium during this study and often has to be requested specifically. Although colour Doppler can be used to detect abnormal flows between the chambers of the heart (e.g., persistent (patent) foramen ovale ), it has a limited sensitivity .
"Bubble contrast TTE" involves the injection of agitated saline into a vein, followed by an Echocardiographic study. The bubbles are initially detected in the right atrium and right ventricle. If bubbles appear in the left heart, it may indicate a shunt, such as a patent foramen ovale , atrial septal defect , ventricular septal defect or ...

The composition of the bubble shell and filling material determine important design features such as buoyancy, crush strength, thermal conductivity, and acoustic properties. They are used in medical diagnostics as a contrast agent for ultrasound imaging . [ 4 ]
Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

But a new study suggests this standard protocol might not be necessary for a common form of early-stage breast cancer. Ductal carcinoma in situ, or DCIS, accounts for up to 25% of diagnosed breast ...
Replication-based protocols have recently obtained much attention in the scientific community, as they can allow for substantially better message delivery ratios than in forwarding-based protocols. These types of routing protocols allow for a message to be replicated; each of the replicas, as well as the original message itself, are generally ...
