Power Doppler Mode
Visualize Blood Flow in Greater Detail
Calculate Percent Vascularity - An Index of Relative Vascular Density
Use in conjunction with 3D-Mode for volumetric information
Power Doppler Mode provides a visual overview and general quantification of vasculature.
- Measurement tools in Power Doppler Mode can calculate percent vascularity - an index of relative vascular density
- Small changes in organ vascularity can be detected with Power Doppler imaging and monitored with progression and regression of pathology or as a response to therapy
Power Doppler is more sensitive than Color Doppler Mode, which makes it the preferred tool for oncologic applications and assessment of percent vascularity.
Power Doppler imaging can be done in conjunction with 3D-Mode to provide volumetric information.
