Computed Tomography Technologist Practice Exam

Question: 1 / 615

Which advantage does the simultaneous injection of saline with contrast provide in CT imaging?

Enhances image contrast

Reduces the likelihood of allergic reactions

Decreases streaking artifacts

The simultaneous injection of saline with contrast provides significant advantages in CT imaging, particularly in enhancing the quality of the images obtained. When saline is injected alongside the contrast agent, it helps to create a smoother pathway for the contrast to travel through the blood vessels. This can effectively reduce the likelihood of streaking artifacts that may arise from uneven distribution of the contrast material. The presence of saline assists in better flushing out blood and other materials that could interfere with the clarity and detail of the images, thereby minimizing artifacts that could obscure diagnostic information.

This technique contributes to clearer imaging results, making it easier for radiologists to interpret scans accurately. It is particularly useful in contrast-enhanced studies where precise visualization of structures is crucial.
