متن کاملCerebral blood flow quantification using vessel-encoded arterial spin labeling
Arterial spin labeling (ASL) techniques are gaining popularity for visualizing and quantifying cerebral blood flow (CBF) in a range of patient groups. However, most ASL methods lack vessel-selective information, which is important for the assessment of collateral flow and the arterial supply to lesions. In this study, we explored the use of vessel-encoded pseudocontinuous ASL (VEPCASL) with mul...
متن کاملVessel-encoded arterial spin-labeling using pseudocontinuous tagging.
A new signal-to-noise ratio (SNR) efficient method is introduced for the mapping of vascular territories based on pseudocontinuous arterial spin labeling (ASL). A pseudocontinuous tagging pulse train is modified using additional transverse gradient pulses and phase cycling to place some arteries in a tag condition, while others passing through the same tagging plane are in a control condition. ...
متن کاملMR Cerebral Angiography Using Arterial Spin Labeling for Dynamic Inflow Visualization and Vessel Selectivity
Introduction: Digital subtraction X-ray angiography (DSA) is a widely used technique for the characterization of cerebral vessels. While MRI and CT can, in principle, provide angiographic information that could replace the riskier DSA study, which requires placement of a catheter for localized contrast injection and high doses of X-ray, these techniques typically lack the vessel selectivity and...
