Fast three-dimensional sodium imaging of human brain.

S Köhler¹, C Preibisch, M Nittka, A Haase.

Abstract

A three-dimensional sodium imaging technique with a minimum echo time of 0.9 ms is described in a 2.0 Tesla whole-body system. The relaxation behaviour in vivo of sodium was analysed: a fast T(2)(*) relaxation component between 1.2 and 1.6 ms and a slow T(2)(*) relaxation component between 7.1 ms and 8.4 ms were quantified in brain tissue of three volunteers. Three-dimensional sodium images of the human brain were acquired in 8.5 min with a resolution of 4.7 x 4.7 x 10 mm (0.2 cc voxel size) and a signal-to-noise ratio of 20 in brain tissue and 30 in cerebrospinal fluid.
