Bolus tracking

A Sagittal MPR of an abdominal aortic aneurysm

Bolus tracking is a technique used in computed tomography imaging, to visualise vessels more clearly. A small bolus of radio-opaque contrast media is injected into a patient via a peripheral intravenous cannula. Depending on the vessel being imaged, the volume of contrast is tracked using a region of interest (abbreviated "R.O.I.") at a certain level and then followed by the CT scanner once it reaches this level. Images are acquired at a rate as fast as the contrast moving through the blood vessels.
