Quantification of myocardial mechanics by tissue phase mapping (TPM) is supposed to provide an improved understanding of cardiac motion and to enable a detailed assessment of myocardial diseases such as cardiac asynchrony and dilated cardiomyopathy. A major limitation of TPM in clinical routine is the long acquisition time.
