Accelerated tagging for the assessment of left ventricular myocardial contraction under physical stress.
A TFEPI-CSPAMM sequence is introduced, which is optimized with respect to acquisition speed and image quality. The sequence is used in a stress study, where a short breath-hold duration is crucial, and tested for reproducibility of deformation parameters extracted by HARP for repeated measurements.
