Systems and Methods for Three-Dimensional Spiral Perfusion Imaging |
| 摘要 |
Some aspects of the present disclosure relate to systems and methods for three-dimensional spiral perfusion imaging. In one embodiment, a method for perfusion imaging of a subject includes acquiring perfusion imaging data associated with the heart of a subject. The acquiring includes applying an imaging pulse sequence with a three-dimensional stack-of-spirals trajectory. The method also includes reconstructing perfusion images from the acquired perfusion imaging data. The reconstructing includes parallel imaging and motion-guided compressed sensing. The method also includes determining, from the reconstructed perfusion images, absolute perfusion values based on time-intensity relationships to quantify myocardial blood flow of the heart of the subject, and generating a quantitative volumetric perfusion flow map based on the determined absolute perfusion values. |

1. A method for perfusion imaging of a subject, comprising:
acquiring perfusion imaging data associated with the heart of a subject, the acquiring comprising applying an imaging pulse sequence with a three-dimensional stack-of-spirals trajectory; reconstructing perfusion images from the acquired perfusion imaging data, wherein the reconstructing comprises parallel imaging and motion-guided compressed sensing; determining, from the reconstructed perfusion images, absolute perfusion values based on time-intensity relationships to quantify myocardial blood flow of the heart of the subject; and generating a quantitative volumetric perfusion flow map based on the determined absolute perfusion values. |
