متن کاملDynamic imaging of the fetal heart using metric optimized gating.
PURPOSE Advances in fetal cardiovascular magnetic resonance imaging have been limited by the absence of a reliable cardiac gating signal. The purpose of this work was to develop and validate metric-optimized gating (MOG) for cine imaging of the fetal heart. THEORY AND METHODS Cine MR and electrocardiogram data were acquired in healthy adult volunteers for validation of the MOG method. Compari...
متن کاملFetal cardiac MRI
Background MRI has been confirmed as an important tool for fetal central nervous system and other diseases. MRI has also emerged as a powerful approach to imaging heart diseases in infants. But fetus with heart diseases diagnosed by MRI has relative rarely been reported. Now most doctors agree that fetal cardiac MRI can provide some additional information when the patient was with some special ...
متن کاملUtility of Cardiac Gating for Pulmonary Perfusion MRI
INTRODUCTION Cardiac motion is a common source of artifacts when imaging the chest with methods such as pulmonary perfusion MRI and pulmonary MR angiography (MRA). To minimize these artifacts, the MR sequence is often ECG-gated such that data are only acquired during a portion of the cardiac cycle when the heart is relatively quiescent; typically during diastole. However, this reduces scan effi...
متن کاملHigh resolution multislice imaging of the fetal heart using iGRASP and MOG
Background Multi-slice CINE MRI is an integral facet of postnatal cardiac examinations, but its application to the fetal heart is hampered by the lack of a fetal cardiac gating signal and the possibility of fetal motion. In this work, a method for reconstructing high spatial and temporal resolution multi-slice images of the fetal heart in a clinically acceptable scan time is presented. The prop...
