Feasibility of magnetic resonance imaging-guided cardiac catheterization, angioplasty, and stenting in a commercial wide-bore 0.55T scanner.

ABSTRACT:

Background

Low-field (0.55T) magnetic resonance imaging (MRI) may allow MRI-guided interventions using available catheterization equipment, as radiofrequency-induced heating of interventional devices is reduced at low field. The purpose of this study was to test the feasibility of real-time MRI-guided right and left heart catheterization (R&LHC) as well as angioplasty and stenting of the inferior vena cava using a commercially available 0.55T MRI system (MAGNETOM Free.Max, Siemens Healthineers AG, Erlangen, Germany) with 80 cm patient bore and maximum gradient amplitude and slew rate of 26 mT/m and 45 mT/m/ms, respectively. A secondary aim was to evaluate three different sizes of magnetic resonance (MR)-visible markers.

Methods

Sheaths were placed in the femoral vein and art
