Is TrueFISP a gradient-echo or a spin-echo sequence?
It is commonly accepted that TrueFISP (balanced FFE, FIESTA) belongs to the class of gradient-echo (GRE) sequences. GRE sequences are sensitive to dephasing effects of the transverse magnetization between the excitation pulse and echo acquisition, and phase coherence is only established directly after and before excitation pulses. However, an analysis of the phase evolution of transverse magnet...
متن کاملGradient echo imaging.
Magnetic resonance imaging (MRI) based on gradient echoes is used in a wide variety of imaging techniques and clinical applications. Gradient echo sequences form the basis for an essential group of imaging methods that find widespread use in clinical practice, particularly when fast imaging is important, as for example in cardiac MRI or contrast-enhanced MR angiography. However, the term "gradi...
متن کاملRapid gradient-echo imaging.
Gradient-echo sequences are widely used in magnetic resonance imaging (MRI) for numerous applications ranging from angiography to perfusion to functional MRI. Compared with spin-echo techniques, the very short repetition times of gradient-echo methods enable very rapid 2D and 3D imaging, but also lead to complicated "steady states." Signal and contrast behavior can be described graphically and ...
متن کاملGradient Spin Echo (GraSE) imaging for fast myocardial T2 mapping
BACKGROUND Quantitative Cardiovascular Magnetic Resonance (CMR) techniques have gained high interest in CMR research. Myocardial T2 mapping is thought to be helpful in diagnosis of acute myocardial conditions associated with myocardial edema. In this study we aimed to establish a technique for myocardial T2 mapping based on gradient-spin-echo (GraSE) imaging. METHODS The local ethics committe...
متن کاملGRASE (gradient- and spin-echo) MR of the brain.
PURPOSE To assess the clinical utility of GRASE (gradient- and spin-echo) MR imaging of the brain by comparing it with the T2-weighted turbo spin-echo technique. METHODS Fifty-three consecutive patients referred for MR imaging of the brain were studied with T2-weighted turbo spin-echo and GRASE techniques, matched for effective echo time (110 milliseconds), echo train length (eight), and spat...
