Arterial Transit Time-corrected Renal Blood Flow Measurement with Pulsed Continuous Arterial Spin Labeling MR Imaging
PURPOSE The importance of arterial transit time (ATT) correction for arterial spin labeling MRI has been well debated in neuroimaging, but it has not been well evaluated in renal imaging. The purpose of this study was to evaluate the feasibility of pulsed continuous arterial spin labeling (pcASL) MRI with multiple post-labeling delay (PLD) acquisition for measuring ATT-corrected renal blood flo...
متن کاملCarotid MR angiography using pulsed continuous arterial spin labeling
Introduction Carotid artery disease is a major cause of cerebral ischemia and infarction. It is routinely assessed using contrast-enhanced magnetic resonance angiography (MRA). Several methods for nonenhanced MRA exist, which may be particularly advantageous in patients with impaired renal function due to the risk of nephrogenic systemic fibrosis. Pulsed arterial spin-labeled (ASL) MRA has been...
متن کاملCerebral perfusion and arterial transit time changes during task activation determined with continuous arterial spin labeling.
Perfusion imaging by arterial spin labeling (ASL) can be highly sensitive to the transit time from the labeling site to the tissue. We report the results of a study designed to separate the transit time and perfusion contributions to activation in ASL images accompanying motor and visual stimulation. Fractional transit time decreases were found to be comparable to fractional perfusion increases...
متن کاملSimultaneous measurement of arterial transit time, arterial blood volume, and cerebral blood flow using arterial spin-labeling in patients with Alzheimer disease.
BACKGROUND AND PURPOSE Cerebral hemodynamics abnormality in Alzheimer disease (AD) is not fully understood. Our aim was to determine whether regional hypoperfusion due to AD is associated with abnormalities in regional arterial blood volume (rABV) and regional arterial transit time (rATT) as measured by quantitative arterial spin-labeling (ASL) with multiple-delay time sampling. MATERIALS AND...
متن کاملCerebral Blood Flow and Transit Time Measured by Quantitative Arterial Spin Labeling: Comparison with O-PET
Introduction Arterial spin labeling (ASL) is a unique MR imaging technique that allows for non-invasive measurement of cerebral blood flow (CBF). Recently, ASL with multiple delay time sampling has become available on clinical MR imagers. Quantitative signal targeting by alternating radiofrequency pulses labeling of arterial regions (QUASAR) is one of such techniques, and allows for quantitativ...
