Background Although the prognostic implications of severe mitral regurgitation (MR) are well recognised, they are less clear in moderate MR. We therefore explored the prognostic impact of both ...

The term dilated cardiomyopathy (DCM) refers to a spectrum of heterogeneous myocardial disorders that are characterized by ventricular dilation and depressed myocardial performance in the absence of ...

For Doppler ultrasound, Vmax and Vmean are the maximum and mean velocities in the sample volume, respectively. Whereas MRI is relatively expensive and most suited to imaging central vessels, Doppler ...

Figure 1. Doppler velocity palette. Inbound velocities (towards the radar) are shaded blue, with pale shades for light winds and dark shades for strong winds. Outbound velocities (away from the radar) ...

An intracranial neurovascular exam is also known as a Transcranial Doppler (TCD) study. TCD is a non-invasive, painless ultrasound technique that uses high-frequency sound waves to measure the rate ...

These appear as radials of incorrect Doppler velocities in the area to the northeast of the radar. Doppler observations can also reveal the presence of flocks of birds over Port Phillip Bay, which ...
