Abstract
The present invention teaches systems and methods for a simple cardiac MRI approach that (1) continuously acquires data; (2) covers the entire heart with high isotropic resolution within a few minutes; and (3) requires no physiological gating and minimal user intervention. Applications of the inventive systems and methods include, but are in no way limited to cardiac cine, myocardial perfusion, coronary MRA, delayed enhancement imaging, myocardial T1-weighted imaging for fibrosis imaging, and myocardial T2-weighted imaging for edema imaging.
Claims20
A method for performing magnetic resonance imaging (MRI) on a subject, comprising performing one or more of the following scans using an MRI machine:
- (a) a scout scan to determine the position of the subject's heart;
- (b) a stress perfusion MRI scan on the subject's heart;
- (c) a cine MRI scan on the subject's heart;
- (d) a rest perfusion MRI scan on the subject's heart;
- (e) a coronary MRA scan on the subject's heart;
- and
- (f) a delayed enhancement MRI scan on the subject's heart;
- wherein (a) one or more scan is performed by using a continuous three dimensional radial acquisition scheme that results in the acquisition of a free-breathing k-space dataset, and (b) image reconstruction for one or more scan is performed using a constrained or compressed sensing scheme, and wherein the method does not require (1) ECG triggering, (2) breath-holding by the subject, or (3) the use of a diaphragm navigator.
A non-transitory machine-readable medium having machine executable instructions for causing one or more processors of a magnetic resonance imaging (MRI) machine, and/or a subsystem configured to function therewith, to execute a method, comprising:
- performing one or more of the following scans:
- (a) a scout scan to determine the position of a subject's heart;
- (g) a stress perfusion MRI scan on the subject's heart;
- (h) a cine MRI scan on the subject's heart;
- (i) a rest perfusion MRI scan on the subject's heart;
- (j) a coronary MRA scan on the subject's heart;
- and
- (k) a delayed enhancement MRI scan on the subject's heart;
- wherein (a) one or more scan is performed by using a continuous three dimensional radial acquisition scheme that results in the acquisition of a free-breathing k-space dataset, and (b) image reconstruction for one or more scan is performed using a constrained or compressed sensing scheme, and wherein the method does not require (1) ECG triggering, (2) breath-holding by the subject, or (3) the use of a diaphragm navigator.
