چکیده

Introduction: Pulsed continuous arterial spin labeling (PCASL) was developed to provide improved label and control efficiencies and reduced RF dose compared to multi-slice CASL with a double adiabatic inversion (DAI) control, thus allowing PCASL to be used at high fields (1, 2). However, PCASL is susceptible to label and control plane aliasing and other artifacts related to the design of its label and control irradiations (1, 3). In this study, the aliasing, off-resonance saturation, and residual signals for PCASL were characterized to identify the optimal operational parameters for PCASL.

Correcting for off-resonance induced degradation of inversion efficiency in pseudo-continuous ASL

Introduction: Pseudo-continuous arterial spin labeling (pCASL) uses a long train of labeling pulses to provide multi-slice cerebral perfusion measurements while compensating for magnetization transfer effects without using additional hardware [1]. The inversion efficiency of pCASL is known to be sensitive to the amount of phase shift (φ) experienced during the time between two consecutive RF pu...

Feasibility of Applying Mb Epi Pcasl for High-resolution Whole Brain Perfusion Imaging at 7t

Target audience: Arterial spin labeling researchers, neuroimaging scientists and clinicians Purpose Ultra high fields, (≥7T), should provide significant advantages for high-resolution whole brain perfusion imaging due to greatly increased blood T1 and signal noise ratio (SNR). However, there exist several challenges: B1 and B0 inhomogeneity, high specific absorption rate (SAR) and shortened T2*...

B0 field inhomogeneity considerations in pseudo-continuous arterial spin labeling (pCASL): effects on tagging efficiency and correction strategy.

Pseudo-continuous arterial spin labeling (pCASL) is a very powerful technique to measure cerebral perfusion, which circumvents the problems affecting other continuous arterial spin labeling schemes, such as magnetization transfer and duty cycle. However, some variability in the tagging efficiency of the pCASL technique has been reported. This article investigates the effect of B(0) field inhomo...

Experimental and Numerical Pore Scale Study of Residual Gas Saturation in Water/Gas Imbibition Phenomena

Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...

Estimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power

Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...
