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.
