Purpose To introduce a true three‐dimensional (3D) tagging technique for the assessment of myocardial tissue motion. Materials and Methods To generate a 3D tagging grid, a complementary spatial modulation of magnetization (CSPAMM) was applied in three spatial directions. Imaging was performed using a conventional fast 3D gradient‐echo sequence. For automatic analysis of the 3D‐CSPAMM data set, evaluation software, based on a 3D extension of the HARP technique, was used. Results Successful application of the 3D‐CSPAMM technique in healthy subjects allowed the accurate determination of quantitative 3D motion patterns in the human heart. Conclusion 3D‐CSPAMM may contribute to the quantification of the local 3D myocardial motion pattern throughout the cardiac cycle. J. Magn. Reson. Imaging 2002;16:320–325. © 2002 Wiley‐Liss, Inc.
