Abstract

We have developed a time-resolved technique for acquiring high quality MR angiograms of the cerebrovascular system. The technique is known as 3D MR DSA and represents a new method for imaging the passage of a contrast agent as it passes through the vessels of interest. This is accomplished by repeatedly and rapidly acquiring data so that a series of volume images may be reconstructed every 2 S to 6 s. The advantages of our approach to contrast-enhanced MRA is that, unlike other non time-resolved techniques, 3D MR DSA does not require synchronization with the intravenous injection.
