Variable Flip Angles and Echo Train Lengths in Segmented 3D-EPI at 3 and 7 Tesla
Purpose: To increase the signal sensitivity (temporal SNR/√acquisition time) of high-resolution functional MRI by means of two novel segmented 3D-EPI modifications: the use of variable flip angles (vFA) and, optionally, the use of variable echo train lengths (vETL) facilitated by employing elliptical k-space subsampling. While vFA has the potential to increase the base signal-to-noise ratio, vE...
متن کاملFast structural brain imaging using an MDEFT sequence with a FLASH-EPI hybrid readout.
A sequence for the fast acquisition of T1 weighted structural brain images with whole brain coverage and isotropic resolution of 1mm is presented. It is based on MDEFT with a FLASH-EPI hybrid readout. Several techniques for artefact suppression are implemented, like echo time shifting, asymmetric k-space sampling, and navigator echo acquisition. It is shown experimentally that the hybrid MDEFT ...
متن کاملSpoiled & Balanced Gradient-Echo Sequences
1 Introduction Rapid imaging sequences are characterized by a fast train of excitation and gradient pulses. Between excitation pulses or within TR, the magnetization is not able to return to its thermal equilibrium. As a consequence, excitation pulses will influence both the remaining transversal and the remaining longitudinal magnetization. The steady-state magnetization of a multi pulse exper...
متن کاملSafely Detecting Device Coupling using Reversed RF Polarization and Pre-Spoiled EPI
Purpose: Patients with many types of common implants, including pacemakers and neurostimulators, are ineligible for MR scans due to the potential for tissue heating arising from RF coupling between the excitation field and their device. The severity of this coupling can be detected by reversing the RF polarization in the birdcage RF receiver. Ideally, this results in MR signal only around coupl...
متن کاملSteady-state sequences: Spoiled and balanced methods
In the context of MRI pulse sequences, the term “steady state” typically refers to the equilibrium condition that evolves when magnetization experiences a train of radiofrequency (RF) pulses. If RF pulses occur at broadly spaced intervals (TR≫T1), the magnetization recovers fully between pulses due to relaxation, and the steady-state is identical to the fully-relaxed magnetization, M0. In gener...
