Evaluation of an MR compatible Doppler-ultrasound device as a new trigger method in cardiac MRI: A quantitative comparison to ECG

Abstract

The aim was to investigate the feasibility to perform cardiac magnetic resonance imaging (MRI) using a MR compatible Doppler-ultrasound (US) device as a new method to trigger the human heart cycle. MRI images were compared between ECG and Dopplerultrasound triggered examination in terms of image quality by an objective measure of acutance and functional assessment. © 2013 by Walter de Gruyter.
