Abstract
The present disclosure is directed to combined angiography and perfusion using radial imaging and arterial spin labeling.
Claims25
A computer implemented method for combined angiography and perfusion imaging using radial imaging, comprising:
- labeling blood for dynamic imaging with arterial spin labeling and without use of a contrast agent;
- acquiring a data set from the labeled blood using radial imaging and a continuous readout scheme;
- reconstructing one or more angiography images from the data set, wherein the one or more reconstructed angiography images are reconstructed with a spatial and temporal resolution for angiography;
- and
- separately reconstructing one or more perfusion images from the data set, wherein the one or more reconstructed perfusion images are reconstructed with a spatial and temporal resolution for perfusion imaging,
- wherein the step of separately reconstructing one or more perfusion images includes separately reconstructing the one or more perfusion images from the same data set from which the one or more angiography images are reconstructed.
3 more elements
A system comprising:
- at least one computing device;
- at least one application executable in the at least one computing device, the at least one application comprising logic that:
- A. labels blood for dynamic imaging with arterial spin labeling and without use of a contrast agent;
- B. acquires a data set from the labeled blood set using radial imaging and a continuous readout scheme;
- C. reconstructs one or more angiography images from the data set, wherein the one or more reconstructed angiography images are reconstructed with a spatial and temporal resolution for angiography;
- and
- D. separately reconstructs one or more perfusion images from the data set, wherein the one or more reconstructed perfusion images are reconstructed with a spatial and temporal resolution for perfusion imaging,
- wherein the step of separately reconstructing one or more perfusion images includes separately reconstructing the one or more perfusion images from the same data set from which the one or more angiography images are reconstructed.
