Dark-rim-free ungated first-pass perfusion CMR with 3-Slice end-systolic imaging: initial experience
Background First-pass perfusion (FPP) cardiac MR (CMR) imaging has been shown to have a high performance for diagnosis of coronary artery disease (CAD). Reliability of FPP imaging, however, is hindered by dark-rim artifacts (DRAs) and the need for near-perfect ECG gating. The latter can be challenging in the presence of arrhythmias or heart-rate variations during stress. Moreover, endsystolic (...

Branch Brain Research Institute, Heidelberg, VIC, Australia, Nathan Kline Institute, Orangeburg, NY, United States, University College London, London, Middlesex, United Kingdom Synopsis: A novel implementation of the QUIPSS II method for quantitative multi-slice perfusion imaging is demonstrated with an optimized saturation scheme based on a double ...
متن کاملInfluence of longitudinal position on the evolution of steady-state signal in cardiac cine balanced steady-state free precession imaging
Background Emerging quantitative cardiac magnetic resonance imaging (CMRI) techniques use cine balanced steady-state free precession (bSSFP) to measure myocardial signal intensity and probe underlying physiological parameters. This correlation assumes that steady-state is maintained uniformly throughout the heart in space and time. Purpose To determine the effects of longitudinal cardiac moti...
متن کاملSteady-state first-pass perfusion (SSFPP): A 3D TWIST in myocardial first-pass perfusion imaging
A new approach to myocardial first-pass perfusion imaging is presented; this technique, called SSFPP, is based on 3D SSFP sequence whereby magnetization is maintained in constant steady-state, while data acquisition is gated to diastole. This results in high SNR and CNR, and other characteristics that can potentially mitigate dark rim artifacts. The high-blood myocardial contrast of SSFP allows...
متن کاملSpiral balanced steady-state free precession cardiac imaging.
Balanced steady-state free precession (SSFP) sequences are useful in cardiac imaging because they achieve high signal efficiency and excellent blood-myocardium contrast. Spiral imaging enables the efficient acquisition of cardiac images with reduced flow and motion artifacts. Balanced SSFP has been combined with spiral imaging for real-time interactive cardiac MRI. New features of this method t...
