Our CT Urogram protocol is made up of three phases, which includes the control, the arterial phase, and the 10Min Delayed phase with the "chaser" (which is an infusion connected immediately after the arterial phase). We have two opinions from two CT clinical specialists in my department. And how does it impact the quality of the study? Any suggestions or references?

I do not use any protocol in my daily practice. I judge by individual because the indications for CT are not the same. If I suspect renal mass , arterial phase + venous phase is essential and may be 3-5 minute delayed phase. If I suspect obstructive uropathy , venous phase and 10 minute delayed phase is enough.
