Perfusion imaging using arterial spin labeling.
Arterial spin labeling is a magnetic resonance method for the measurement of cerebral blood flow. In its simplest form, the perfusion contrast in the images gathered by this technique comes from the subtraction of two successively acquired images: one with, and one without, proximal labeling of arterial water spins after a small delay time. Over the last decade, the method has moved from the ex...
متن کاملBreast Perfusion Imaging Using Arterial Spin Labeling
Delay 2 s Fig. 1. ASL experiment from a volunteer at 1.5T. (a) The imaging slice and labeling slab are depicted by yellow and blue boxes. (b) Fat-saturated SPGR image. Perfusion images are shown in (c-e) for delay times of 1 s, 1.5 s and 2 s. Arteries located close to the skin are depicted well; however, perfusion in glandular tissue is hardly visible. The yellow arrow shows an artery which doe...
متن کاملRenal Perfusion Imaging using Continuous Arterial Spin Labeling with Separate Labeling and Imaging Coils
Introduction: Assessment of renal perfusion rates can provide important information about kidney function, but also about diseases with pathological perfusion changes, e.g. nephrocalcinosis and renal infarction. To minimize potential risks of nephrotoxicity associated with Gd-based MR perfusion techniques, arterial spin labeling (ASL) is currently being adapted to the kidneys [1-3]. ASL, a meth...
متن کاملQuantitative mouse renal perfusion using arterial spin labeling.
Information on renal perfusion is essential for the diagnosis and prognosis of kidney function. Quantification using gadolinium chelates is limited as a result of filtration through renal glomeruli and safety concerns in patients with kidney dysfunction. Arterial spin labeling MRI is a noninvasive technique for perfusion quantification that has been applied to humans and animals. However, becau...
متن کاملPediatric perfusion imaging using pulsed arterial spin labeling.
PURPOSE To test the feasibility of pediatric perfusion imaging using a pulsed arterial spin labeling (ASL) technique at 1.5 T. MATERIALS AND METHODS ASL perfusion imaging was carried out on seven neurologically normal children and five healthy adults. The signal-to-noise ratio (SNR) of the perfusion images along with T1, M(0), arterial transit time, and the temporal fluctuation of the ASL ima...
