A
new 4D MRA technique called Contrast-enhanced Angiography with Multi-Echo and
RAdial k-space (CAMERA) is introduced.
With CAMERA, temporal footprint is reduced by a factor of 2 without
parallel imaging or undersampling, while increasing SNR. Higher frame rates are achieved by radial
sliding window reconstruction. Further
acceleration is also possible by incorporating parallel imaging. The technique has been applied to MRA in
the intracranial, pulmonary, and renal vessels.
