Improved Myocardial Sodium Quantification at <scp>7 T</scp> Using Interleaved <scp> ²³ Na </scp> / <scp> ¹ H pTx MRI </scp> With Motion and Anatomy‐Based <scp> B ₁ </scp> Correction

The combination of retrospective motion correction and anatomy-based B₁ bias field correction enables repeatable myocardial sodium quantification at 7 T. The interleaved acquisition facilitates robust segmentation and efficient use of ¹H MRI for motion and B₁ correction, providing a scalable framework for future clinical research studies.
