Speckle-Tracking Strain: Clinical Utility and Future Directions
Speckle-tracking strain is an increasingly used echocardiographic technology that can provide additional (if not potentially incremental) clinical utility. Interpretation of speckle-tracking strain must take into consideration both technical and clinical sources of variability. This technology is a focus of much current research, with the prospect of exciting future developments that are eagerly awaited. 3D = 3-dimensional.
