Nonenhanced Time-resolved Mra Using Inflow Arterial Spin Labeling
Introduction A pulsed arterial spin labeling (ASL) technique is useful for obtaining hemodynamics information as well as tissue perfusion without using contrast materials and there are various methods have proposed [1-4]. In the standard ASL techniques, subtraction between a tag pulse and a control pulse is required to enhance blood vessels while subtracting out the background signals. However,...
متن کاملApplication of Time-Resolved 3D Digital Subtraction Angiography to Plan Cerebral Arteriovenous Malformation Radiosurgery.
BACKGROUND AND PURPOSE Time-resolved 3D-DSA (4D-DSA) enables viewing vasculature from any desired angle and time frame. We investigated whether these advantages may facilitate treatment planning and the feasibility of using 4D-DSA as a single imaging technique in AVM/dural arteriovenous fistula radiosurgery. MATERIALS AND METHODS Twenty consecutive patients (8 dural arteriovenous fistulas and...
متن کاملIntravenous angiography using digital video subtraction: intravenous cervicocerebrovascular angiography.
The clinical application of intravenous angiography to study the cervicocerebrovascular system using the digital video subtraction system described in a companion article is reported. About 0.75 ml/kg of a standard 76% iodine contrast solution is injected into an antecubital vein using a power injector. Then 15-20 exposures of the head and neck region at a 1/sec rate are made on the image inten...
متن کاملAccelerated Time Resolved Inflow with 3D Multi-Echo Radial Trajectories
Introduction: Arterial spin labeling (ASL) sequences which utilize tagging schemes to images the flow of blood have emerged as effective techniques for the non-contrast angiography; however, these techniques typically suffer from long acquisition times, sensitivity to tag delay parameters, and uncertain performance in cases of complex flow [1-3]. To mitigate these errors, we have previously dem...
متن کاملTime-resolved contrast-enhanced 3D MR angiography.
An MR angiographic technique, referred to as 3D TRICKS (3D time-resolved imaging of contrast kinetics) has been developed. This technique combines and extends to 3D imaging several previously published elements. These elements include an increased sampling rate for lower spatial frequencies, temporal interpolation of k-space views, and zero-filling in the slice-encoding dimension. When appropri...
