Abstract
A method for equilibrium phase contrast-enhanced magnetic resonance (MR) angiography using an extracellular MR contrast agent administered to a subject includes performing a balanced Trelaxation enhanced steady-state (bTRESS) pulse sequence to acquire MR data from a region of interest of the subject during an equilibrium phase of contrast enhancement after a first pass of the extracellular contrast agent through the region of interest. The bTRESS pulse sequence includes a T-weighted magnetization preparation including at least one contrast modifying (CM) radio frequency (RF) pulse, a single-shot balanced steady-state free precession (bSSFP) readout, and a time interval between the T-weighted magnetization preparation and the acquisition of a center of k-space. The time interval is determined based on a Trelaxation time of a contrast-enhanced blood pool and a flip angle of the at least one CM RF pulse. The method further includes generating an angiographic image of the region of interest.
