Technical impact of mechanical indicators on left ventricular echocardiography.

Apical four-chamber images recorded in a patient demonstrating the impact of mechanical indices appears to contrast. 

Above: 

The recorded image has a mechanical index of 0.3 and shows translucency of all four chambers of the heart. 

Below: 

The image was recorded 10 seconds later with a mechanical index of 1.0. Note the complete lack of contrast in the near regions and the partial fill vortex in the distal regions.
