Please advise on a siemens 64 slice dual source definition what arterial delay you should use for Hepatocellular carcinoma.

If we bolus track where would you set the roi and what should the HU units be set at?

Also, what delay after the tracker triggers should we use?

Preaching to the choir, but thank you very much for sharing your expertise and maintaining such a wonderful and useful site!!!

Given the UCSF paper, what kind of time delay to you use at JHU between ingestion and scanning? Our practice is similar to the UCSF quote, but it would sure be nice to get a longer delay in there to opacify distal SB loops.
