Additional Role of 3D ASL Perfusion in Skull Base Lesions

Indian Journal of Radiology and Imaging
Background Arterial spin labeling (ASL) perfusion imaging is widely used since its main advantage is that no intravenous contrast is needed.

Perfusion magnetic resonance imaging provides additional information as compared to anatomical imaging for decision-making in vestibular schwannoma

European Journal of Radiology Open, 2016
Objective: The added value of perfusion MRI for decision-making in vestibular schwannoma (VS) patients is unknown. MRI offers two perfusion methods: the first employing contrast agent (dynamic susceptibility contrast (DSC)-MRI) that provides information ...

Arterial spin labeling in clinical pediatric imaging

Diagnostic and Interventional Imaging, 2016
Arterial spin labeling (ASL) perfusion-weighted magnetic resonance imaging is the only approach that enables direct and non-invasive quantitative measurement of cerebral blood flow in the brain regions without administration of contrast material and without radiation. ASL is thus a promising perfusion imaging method for assessing cerebral blood flow in

Magnetic resonance imaging of cerebral blood flow in animal stroke models

Brain Circulation, 2016
Perfusion could provide useful information on the metabolic status and functional status of tissues and organs. This review summarizes the most commonly used perfusion measurement methods: Dynamic susceptibility contrast (DSC) and arterial spin labeling (

Arterial Spin Labeling Techniques 2009–2014

Journal of Medical Imaging and Radiation Sciences, 2016
Arterial spin labeling (ASL) techniques have been implemented across a diverse range of clinical and experimental applications. This review aims to evaluate the current feasibility of ASL in clinical neuroradiology based on recent improvements to ASL sequences and highlight areas for potential clinical applications.In December 2014, a literature search

Quantitative myocardial perfusion in mice based on the signal intensity of flow sensitized CMR

Journal of Cardiovascular Magnetic Resonance, 2012
Background In the conventional approach to arterial spin labeling in the rodent heart, the relative difference in the apparent T1 relaxation times corresponding to selective and non-selective inversion is related to perfusion via a two compartment model ...

Evaluating Vascular Hemodynamics in Cerebral Proliferative Angiopathy Using Advanced Arterial Spin Labeling MRI

Stroke: Vascular and Interventional Neurology
Cerebral proliferative angiopathy (CPA) is a rare vascular disorder that affects normal blood circulation in the brain. Although the structural changes in CPA can be characterized using standard radiologic modalities, assessing the vascular hemodynamics ...
