3D quantitative myocardial perfusion imaging with hyperpolarized HP001(bis‐1,1‐(hydroxymethyl)‐[1‐<sup>13</sup>C]cyclopropane‐d8): Application of gradient echo and balanced SSFP sequences
This study demonstrated the feasibility of 3D whole-heart myocardial perfusion quantification using hyperpolarized HP001 with both GRE and bSSFP sequences.
