ClearRead CT | Vessel Suppress

ClearRead CT Vessel Suppress produces a secondary series, suppressing vessels and other normal structures within the lungs to improve nodule conspicuity as shown in the image to the right. The Vessel Suppress series gives users access to a truly unique and patented technology that aids in improving reading accuracy and efficiency. The processed series can be easily linked with the original CT series for synchronized scrolling.

Vessel Suppress not only enables improved nodule detection by eliminating obscuring normal structures, it also allows improved nodule characterizations for all nodule types.1 Improved characterization derives in part from the ability for precise segmentation of nodule boundaries. Aside from volumetrics, the Vessel Suppress series enables a unique view of nodules.

ClearRead CT aided radiologists perform nodule search 26% faster and detect 29% of previously missed actionable nodules.*

Simple integration and implementation

Simple installation

Enterprise wide capability powered by acquisition normalization technology that allows “plug in” capability across all CT manufacturers and diverse imaging protocols.


High throughput, scalable, computation with “off the shelf” hardware or virtual machine deployments.

Easier detection

Aids to the radiologist in seeing and characterizing solid, sub-solid and ground glass nodules and potentially other types of focal densities associated with other disease and infections in the lungs.
