Abstract

Dual Energy bone removal and plaque removal are useful tools for peripheral run-off CT-angiography. Dual Energy bone removal shows significant advantages over software-based bone removal tools with less vessel segmentation errors, especially in the lower leg, where small vessels may run directly adjacent to the bones. It is a “one-click application”, works without user interaction, and therefore, shows high practicability for clinical routine. Bone-removed MIPs of peripheral arteries may serve as a useful tool for a fast evaluation of large datasets and provide a good overview for surgical planning in patients suffering from PAD.
