Clinical use

Carotid Duplex interpretation support

Society of Radiologists in Ultrasound support for grading ICA stenosis on duplex ultrasound.

  • SRU interpretation is multiparametric. PSV drives the primary branch, while plaque, ICA/CCA PSV ratio, EDV, and direct lumen assessment help resolve discordant cases.

Inputs

Plaque or intimal thickening visible
Markedly narrowed residual lumen / near occlusion
No detectable patent lumen or flow
