Which bolus method is considered more efficient for CT imaging?

Bolus triggering is considered the most efficient bolus method for CT imaging due to its ability to synchronize the administration of contrast material with the actual imaging sequence. This method allows the technologist to set a predetermined threshold for the enhancement of a specific area of interest. When this threshold is reached during the scan, the CT machine can automatically trigger the acquisition, ensuring that the images are taken at the optimal time when contrast is at the right level within the vascular structure.

This precision minimizes the excess contrast needed and enhances image quality by ensuring that the contrast is present in the area being imaged at the right moment, resulting in better diagnostic outcomes. In contrast to other methods, bolus triggering streamlines the process and enhances overall efficiency during the imaging procedure, which can be particularly valuable in emergency settings or complex cases where timing is critical.
