Feasibility of acoustically triggered cine imaging for global cardiac function assessment using an MR-stethoscope
- As high-field cardiac MRI becomes more widespread the propensity of ECG recordings to interference from electromagnetic fields increases and with it the motivation for a practical gating/triggering alternative. This study explores the feasibility, efficacy and reliability of acoustic cardiac triggering (ACT) for 2D CINE SSFP imaging at 1.5 T and 3.0 T including left ventricular function and endocardial border sharpness assessment. The MR stethoscopes intrinsic insensitivity to interference with electro-magnetic fields and hydro-dynamic effects renders it suitable for assessment of global cardiac function due to its excellent trigger reliability even at high magnetic field strengths.
