CAMRT Radiography Practice Exam

Which of the following is NOT one of the 5 injection parameters for an automatic contrast medium pressure injector?

1. Flow Rate

2. Temperature

3. Injection Pressure

4. Total Volume

The correct answer is: Temperature

The injection parameters for an automatic contrast medium pressure injector are critical in ensuring that the contrast medium is delivered effectively and safely during imaging procedures. These parameters typically include flow rate, injection pressure, and total volume. Flow rate refers to the speed at which the contrast medium is administered, which must be optimized to ensure proper visualization of the anatomy being imaged. Injection pressure is also crucial, as it must be maintained within a specific range to ensure adequate distribution of the contrast medium without causing injury to the patient’s vascular system. Total volume indicates the amount of contrast medium to be infused and is important for achieving the desired imaging results. Temperature, however, is not typically considered one of the five key parameters for the operation of an automatic contrast medium pressure injector. While it is essential to ensure that contrast media is stored at recommended temperatures for stability and safety, the temperature at which it is administered is not a specific parameter that is adjusted or monitored during the injection process. Understanding these parameters is vital for radiographers as they impact the effectiveness and safety of the imaging procedure.
