Method for temporally resolved, three-dimensional MR volume acquisitions

摘要

Disclosed is an apparatus and a method for three dimensional magnetic resonance data acquisitions using a fast 3D sequence to acquire volumetric data in a cine mode. The entire heart can be imaged in the same amount of time that a conventional cine scan requires for a single section. The true temporal resolution is similar to that of the segmented k-space acquisition. The sequence uses very short repetition times (TR), and hence the inherent contrast is poor. This problem is overcome with the use of a T1 shortening agent. Since contrast between blood and the myocardium is no longer flow dependent, it is more stable throughout the heart cycle.
