Fast 3D cardiac cine MR imaging

J Magn Reson Imaging. 1999 May;9(5):751-5. doi: 10.1002/(sici)1522-2586(199905)9:5<751::aid-jmri21>3.0.co;2-7.

Abstract

We describe a technique for three-dimensional cine MR imaging. By using short repetition times (TR) and interleaved slice encoding, volumetric cine data can be acquired throughout the cardiac cycle with a temporal resolution of approximately 80 msec. A T1-shortening agent is used to produce contrast between blood and myocardium. A comparison between the acquisition times of this and several other two-dimensional techniques is presented.
