Implication

Innovative DART technique quantifies dynamic T1 values in myocardium, indicating effectiveness of gadolinium enhancement.

Key Points

  • The DART sequence enables successful tracking of dynamic T1 values in myocardium and enhances tissue characterization.
  • Dynamic T1 values were quantified in both phantom and in-vivo studies, demonstrating method validation.
  • Free-breathing acquisition allows for a single scan to obtain dynamic and stable phase information effectively.
  • This method highlights the potential for improved myocardial assessment during early gadolinium enhancement.
