What is the term rate rise in injection?

A rate rise is another way that a power injection of contrast material can be modified and describes the time in seconds that it takes from the beginning of the injection to reach the desired injection rate. For an injection of “20 for 40” with no rate rise, the velocity of contrast agent in the catheter immediately jumps from 0 to 20 mL/s. That is, no rate rise implies a step function. If a rate rise of 0.6 second is used, it takes 0.6 second for the injection to reach maximum velocity. Rate rises are used to minimize the recoil of the catheter during rapid injections.
