2.3.4 – Quiz: Carotid Stenosis Grading Morphological Method

Atherosclerotic plaque primarily occurs:

The morphologic method to assess the stenosis degree:

The morphologic method used to assess the stenosis degree:

The luminal reduction of the ICA caused by atherosclerotic plaque can be calculated using measurements taken:

The percentage of area reduction to grade stenosis is measured according the following formula:

The morphologic grading methods should only be used to grade stenosis with:

The NASCET method:

The ECST method:

The two degrees of stenosis measured with ECST and NASCET methods can be easily converted into each other using the following formula:

When measuring area reduction in transverse plane, the operator is likely to:

The morphologic method:

Colour flow Doppler used in the assessment of a carotid stenosis with the morphologic method:
