Overview

This study demonstrates improved mapping quality in myocardial imaging using a self-navigated technique, suggesting better outcomes for patients with respiratory motion.

Key Points

  • Through-plane respiratory motion is effectively corrected in the proposed 2D free-running myocardial mapping technique, improving image quality.
  • Numerical simulations indicate that dual flip angles can minimize mapping estimation errors, leading to superior uniformity in imaging.
  • The phantom experiments showed strong correlation with reference methods, validating the repeatability of the free-running estimation regardless of heart rates.
  • A short scan time of 46 seconds allows the technique to achieve quality mapping comparable to conventional methods without breath-holding.
