Abstract
To generate a magnetic resonance angiograph, a patient is injected with a contrast-enhancing agent ( ). An ellipsoidal central portion of k-space ( ) and a first surrounding region ( ) are continuously sampled ( ). A portion of each central data set ( ) is reconstructed ( ) into a low-resolution volume and maximum-intensity-projected ( ) onto a line. The maximum intensity projection ( ) is processed ( ) in order to detect the arrival of the contrast enhancing bolus within a volume of interest. Upon detection of the arrival of the bolus, the acquisition of a high-resolution magnetic resonance angiograph is triggered ( ) in which higher phase encode portions ( ) of k-space are sampled. The central data set ( ) along with the higher phase encode views ( ) are reconstructed ( ) into a high-resolution magnetic resonance angiogram. The present technique allows for substantially zero latency between the detection of the contrast-enhancing agent bolus and the acquisition of the magnetic resonance angiogram.
