Combined use of the intravascular blood‐pool agent, gadomer, and carbon dioxide: A novel type of double‐contrast magnetic resonance angiography (MRA)

Abstract

Due to T1-shortening, the circulating blood-pool agent prevents flow artifacts during catheter manipulations because the steady-state is reached much earlier. Therefore, this double-contrast MRA method improves catheter conspicuity and might be helpful for guiding and controlling intravascular procedures during interventional MRI.
