Non-invasive assessment of cerebral blood flow using selective MR-Arterial Spin Labeling (ASL): First Experience

Introduction: The assessment of cerebral blood flow (CBF) using non-invasive MR methods may increase the insight of the pathophysiological mechanism that leads to disease as well as to the understanding of the development of diseases. Arterial Spin Labeling (ASL) is a fast developing technique with a wide range of applications in the field of neuroradiology and neurology. ASL is a fast technique, precise in spatial resolution and it provides basic quantities in units of ml/100g/min. Recent advances in ASL have permitted noninvasive evaluation of vascular territories for the evaluation of collateral blood flow in…
