Abstract

A region of interest of a subject is disposed in an imaging region ( ) of a magnetic resonance imaging apparatus. A contrast material ( ) is injected into the subject. An operator initiates a series of fast scan imaging sequences to track the position for entry of the contrast material, into the region of interest. A trajectory through a k-space is selected for the fast scan imaging sequences that both generates data lines for the fast scan images and oversamples a common data point ( ). A peak intensity of the oversampled common point ( ) indicates that the bolus of contrast agent ( ) has arrived. A sequence controller ( ) initiates a diagnostic imaging sequence ( ). The operator views the fast scan image and has the option to abort the diagnostic sequence ( ) if the fast scan image does not verify that the contrast agent has arrived in the region of interest. The system continues to taking fast scan images until the arrival of the bolus of contrast agent has been verified.
