Exploring the Pros and Cons of Post-Processing in Contrast-Enhanced Dual-Energy Neck CT Scans.
To learn the pros and cons of dual-energy post-processing techniques in contrast-enhanced CT-scans of the neck. To understand the background how Perfused Blood Volume (PBV), Virtual Non-Contrast (VNC) and mono-energetic reconstructions are made. To demonstrate the benefits of the several post-proces[...]
Since the introduction of dual-energy with a dual source CT scanner (Figure 1), new ways of receiving extra information came available beyond just the gathered scans and mixed datasets. By post-processing these dual-energy scans on a workstation, with help of a post-processing client, we are able[...]
Findings and procedure details:
Twenty-four neck cases from 2017 which were scanned with dual-energy in our clinical practice were observed by a radiologist with years of experience with head and neck CT. These cases were examined for the pros and cons of using the extra reconstruction techniques in the form of PBV 75% overlay and[...]
Dual-energy provides extra information and can reduce metal artifacts which can lead to better diagnosis or therapy decision making. Dose efficiency, workflow, quality and motion suitability may vary with different patients and protocols. Therefore the use of dual-energy over a standard CT should [...]
