Tissue Phase Mapping (TPM) is a well-established technique to assess regional cardiac function in humans and in animal models such as mice. While TPM-studies in humans required suppression of the dominant blood signal in order to provide an accurate measurement of myocardial velocities, the murine studies were conducted without blood suppression. We show that bright-blood contrast can impact on both, absolute velocities and motion pattern, which can potentially and erroneously be identified as a local impairment of cardiac function.
