Abstract

Purpose

To develop a fast and highly automated method for calculating two‐dimensional myocardial motion and deformation using velocity encoded magnetic resonance imaging.

Materials and Methods

Two‐dimensional phase contrast magnetic resonance imaging was used to acquire time resolved velocity maps of the myocardium. Cardiac motion was calculated by an iterative integration–regularization scheme of low computational cost. Image segmentation was performed using active appearance models.

Results

Validation of motion tracking was performed in N = 47 subjects using saturation grid‐tagging and closely followed “tag‐lines.” Image segmentation was validated vs. manual delineation.

Conclusion

The speed and limited user interaction gives the method good potential for use in clinical practice. J. Magn. Reson. Imaging 2006. © 2006 Wiley‐Liss, Inc.

## Abstract Time‐resolved velocity imaging using the magnetic resonance phase contrast technique can provide clinically important quantitative flow measurements __in vivo__ but suffers from long scan times when based on conventional spin‐warp sequences. This can be particularly problematic when ima
