Abstract
A phase-contrast MRI (PC-MRI) system and method employing a Hybrid One- and Two-sided Flow Encoding Only (HOTFEO) acquisition scheme for accurate blood flow and velocity measurements of three-directional-velocity-encoding PC-MRI.
Claims20
An apparatus for time-resolved PC-MRI of a target anatomy, the system comprising:
- (a) a computer processor;
- and
- (b) a non-transitory computer-readable memory storing instructions executable by the computer processor;
- (c) wherein said instructions, when executed by the computer processor, perform steps comprising:
- (i) performing one-sided flow-encoded (FE) MRI acquisition of the target anatomy in a first direction of three orthogonal directions associated with an MRI scanner;
- (ii) performing interleaved, two-sided FE MRI acquisition of the target anatomy in a second direction of the MRI scanner;
- and
- (iii) generating successive time-resolved FE datasets of the target anatomy from the one-sided FE MRI acquisition and interleaved, two-sided FE MRI acquisition.
