Prospective swallowing motion self-gating: a feasibility study in carotid artery wall MRI using 3D variable-flip-angle TSE
نویسندگان
چکیده
Background 3D black-blood MRI is a promising imaging modality for carotid artery wall imaging but is inherently susceptible to motion. Previous work shown that swallowing can result in the greatest motion at the carotid bifurcation and its vicinity (1). A self-gating (SG) method in combination with a 3D variable-flip-angle turbo spinecho sequence, SPACE, has recently been proposed for gating swallowing motion (2). This work aimed to validate the utility of the new technique on healthy volunteers and patients.

Prospective Self-Gating To Eliminate Motion Artifacts in 3D Carotid Artery Wall Imaging
Introduction: 3D variable-flip-angle TSE (SPACE) has been proposed for carotid vessel wall imaging [1]. However, a relatively long imaging time renders this technique more prone to image artifacts caused by apparent motion such as swallowing. Self-gating technique [2] has recently been used to exclude data acquired during swallowing, yet two shortcomings remain. First, a single self-gating (SG)...

Introduction In vivo MR carotid plaque imaging has been used to identify vessel morphology and plaque characteristics, and their associations with clinical symptoms. [1] Two-dimensional T1 weighted (T1W) double inversion recovery spin echo [2] and subsequently quadruple inversion recovery spin echo sequences [3] have been used to obtain the contrast between vessel wall and lumen, and identify c...
متن کاملThree-dimensional Whole-Heart Cine MRI using Prospective Self-Gating for Compensation of Cardiac and Respiratory Motion
Introduction: Two-dimensional (2D) breath-hold and ECG-triggered cine MRI is frequently used to assess cardiac function. However this technique requires cooperation from the patient, and the MR acquisition has to be synchronized with the cardiac cycle using ECG. To control respiratory motion, the subject has to perform breath-holds or the position of the diaphragm has to be tracked using a resp...
