Impact of mechanical indicators on left ventricular echocardiography
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.
The recorded image has a mechanical index of 0.3 and shows translucency of all four chambers of the heart.
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.
