Abstract

Gadolinium (Gd)-enhanced three-dimensional (3D) magnetic resonance angiography (MRA) is a quick method for performing noninvasive diagnostic angiography. A major technical obstacle to the successful implementation of this technique, however, is the proper coordination of the data acquisition with the contrast bolus. In this article, the use of an automated bolus- detection algorithm (MR SmartPrep), which triggers the initiation of data acquisition for Gd-enhanced 3D MRA is reviewed. Potential applications of this evolving technique are illustrated.
