Vessel suppression on chest CT: Seeing what’s underneath the plumbing

Abstract
Philips CT Clinical Science Philips Healthcare • USA

Wiemker R, Buelow T, Klinder T, Dharaiya E, Steinberg A, Rabotnikov M. 

Purpose/Aim
To demonstrate that a lung visualization with gradual suppression of the vessels reveals a clearer view on the underlying small vasculature, parenchyma, and nodular anomalies, without using explicit computer aided detection (CAD) markers.

Content Organization  
  1. CT screening for high risk groups may decrease lung cancer mortality.
  2. Explanation of the visualization concept:
    1. No explicit detection and segmentation of vessels or nodules which might cause false positives and negatives and clutter the image with markers.
    2. Instead: subtle and gradual subduing of voxels belonging to tubular image structures, based on local shape properties computed on multi-resolution levels.
  3. Graphical User Interaction
    1. Mouse-click navigation between overview rendering to original CT slice location and vice versa
    2. Switching between different suppression strength options.
  4. Case studies. 
Summary 
As a complementary viewing mode, the opacity of the larger lung vessels can be weakened in a subtle way such as to implicitly make nodules and other anomalies visually more prominent. The resulting vessel-suppressed slab MIPs appear very similar to standard MIPs, but less dominated by vasculature.
