An established setting for a MCE stress test with the Philips IE 33 platform (german software version)
With the default setting “adult echo” the X5-1 probe is activated with a mechanical index of 1.1
|With the button “Perfusion” in the fourth row MCE settings are activated.||Mechanical index MI is depicted on the top at the right side of the screen, as default here 1,1|
Choosing the menue “contrast MI low” in the bottom line the setting for MCE can be modified on the right sreen:
With “flash-images” 8 to 15 frames with high mechanical index (MI 0.97 – 1.28) can be selected to destroy the bubbles. The recording of the MCE images follows with an MI of 0.09 – 0.1 . Setup for this platform has been stored under the menue “Perfusion” and is displayed on the start screen as menue point 4 in the second line from the bottom.
|fokus mitral valve, flash images 8 – (15), flash MI 0.97 – 1.28, following MI of 0.1.||Top right in the second row shows mechanical index during “flash” (in this example 0.97) and in the first row MI during “low MI” imaging (here 0.1)|
Using the button “weiter ->” a sceen with further menues is opened:
|We use “chromascale 2” and grey scale “1”.
With “Mittelung hoch” the images become “smooth”, less “pixelated” and a perfusion defect may be easier to recognize.
