Multiple Acquisition Fat-Saturated Balanced Steady State Free Precession Imaging
INTRODUCTION While balanced-SSFP (bSSFP) imaging is advantageous in its ability to produce high SNR in short imaging times, its clinical application has been limited due to several well-known shortcomings. The bright signal from fat is typically unwanted, and the short repetition times (TRs) required to avoid banding artifacts lead to limitations in the achievable resolution. This is especially...
متن کاملImaging periodic currents using alternating balanced steady-state free precession.
Existing functional brain MR imaging methods detect neuronal activity only indirectly via a surrogate signal such as deoxyhemoglobin concentration in the vascular bed of cerebral parenchyma. It has been recently proposed that neuronal currents may be measurable directly using MRI (ncMRI). However, limited success has been reported in neuronal current detection studies that used standard gradien...

متن کاملFlow effects in balanced steady state free precession imaging.
An analysis of the effect of flow on 2D fully balanced steady state free precession (SSFP) imaging is presented. Transient and steady-state SSFP signal intensities in the presence of steady and pulsatile flow were simulated using a matrix formalism based on the Bloch equations. Various through-plane flow waveforms and rates were modeled numerically considering factors such as the excitation sli...
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...
