MR regional perfusion imaging: visualizing functional collateral circulation.
نویسندگان
چکیده
SUMMARY We applied regional perfusion imaging (RPI), a new arterial spin-labeling MR imaging method that selectively studies regions of the brain perfused by individual carotid and basilar arteries. In a patient with cerebrovascular disease, RPI showed cerebral tissue perfused by pial collateral vessels, thereby demonstrating the relationship between anatomic and functional information, which was lacking in conventional x-ray angiography. RPI may be useful to study functional collateral circulation and hence guide therapy in ischemic disease.

Brain ischemia: CT and MRI techniques in acute ischemic stroke.
Imaging plays a central role for intravenous and intra-arterial arterial ischemic stroke treatment patient selection. Computed tomography (CT) / CT angiography or magnetic resonance (MR) / MR angiography imaging are used to exclude stroke mimics and haemorrhage, to determine the cause and mechanism of stroke, to define the extension of brain infarct and to identify the arterial occlusion. Imagi...
متن کاملCollateral circulation imaging: MR perfusion territory arterial spin-labeling at 3T.
BACKGROUND AND PURPOSE Current knowledge of the collateral circulation remains sparse, and a noninvasive method to better characterize the role of collaterals is desirable. The aim of our study was to investigate the presence and distal flow of collaterals by using a new MR perfusion territory imaging, vessel-encoded arterial spin-labeling (VE-ASL). MATERIALS AND METHODS Fifty-six patients wi...
متن کاملPerfusion- and diffusion-weighted MR imaging-guided therapy of vertebral artery dissection: intraarterial thrombolysis through an occipital vertebral anastomosis.
Management of arterial dissections can be particularly challenging. We report a case of vertebral artery dissection in which perfusion- and diffusion-weighted MR imaging findings suggested the presence of salvageable tissue, despite that the patient had symptoms for more than 40 hours. Direct access to the distal vascular territory was unattainable, and the presence of collateral circulation th...
متن کاملRole of Genetic Variation in Collateral Circulation in the Evolution of Acute Stroke
Collateral vessels are anastomoses that connect adjacent arterial trees and reroute perfusion around obstructed arteries or veins. Variation among individuals in the extent of native collaterals (ie, number or diameter) may serve as a prognostic determinant of stroke severity and improve clinical risk benefit decisions for treatment options. Angiographic studies grading collateral circulation i...
متن کاملQuantitative assessment of external carotid artery territory supply with modified vessel-encoded arterial spin-labeling.
BACKGROUND AND PURPOSE In patients with carotid stenosis or occlusion, cerebral blood could be supplied through collateral pathways to improve regional blood flow and protect against ischemic events. The contribution of collaterals from the ICA can be assessed by depiction of vascular perfusion territories with ASL. However, so far there is no method available to evaluate the collateral perfusi...
