| 摘要 |
The present invention is a technique and apparatus for monitoring and detecting the arrival of a contrast agent in a region of interest (e.g., an artery or tissues of interest). In one embodiment, upon detecting a maximum, substantially elevated or elevated concentration of contrast agent in the region of interest, a predetermined portion of the magnetic resonance image data (e.g., data which is representative of the center of k-space) may be acquired. Thus, the present invention may be employed to facilitate synchronization between collecting the central portion of k-space image data with the arterial phase of contrast enhancement.
