Making sense of the CT Urogram

Author: Hiram Shaish

Published in: European Radiology | Issue 3/2020

Key Points

• There is great variation in the CT urogram protocol throughout the literature.

• The study by Renard-Penna et al provides a useful rigorous expert consensus on CT urography technique.

• The study by Rud et al suggests that the excretory phase may not be as necessary as previously thought for visualizing upper tract urothelial carcinoma.
