Demonstrates that 3D affine motion correction enables 100% scan efficiency in Cartesian coronary MRA, indicating potential for faster and predictable cardiac imaging.
We demonstrate the feasibility of a new 3D affine respiratory motion correction technique for Cartesian whole-heart CMRA that achieves 100% scan efficiency and therefore a predictable acquisition time. This approach yields image quality comparable to that of an 8-mm navigator-gated acquisition with lower scan efficiency. Further evaluation of this technique in patients is now warranted to determine its clinical use.
