The 3D TRICKS method for contrast-enhanced, time-resolved MR DSA has been recently described. In this paper, computer simulations are used to investigate the relative frame rate, temporal window, artery-vein temporal separation, contrast-to-noise ratio, and spatial resolution of TRICKS and conventional scans for breath-hold and non-breath-hold applications. For non-breath-hold applications, TRICKS can be configured to provide increased CNR or spatial resolution at an increased frame rate, but with a longer temporal window when compared with a series of conventional scans in which the central portion of k-space is sampled at the same rate as for the TRICKS scans. For breath-hold applications, TRICKS typically provides three images with 75% of the conventional single acquisition spatial resolution and is more tolerant of variations in contrast curve shape within the field of view.
