Arterial Spin Labeling MRI for Assessing Blood Perfusion in the Human Eye Repeatability Study and Clinical Application

The MRI perfusion imaging using arterial spin labeling (ASL)'s non-invasive technique (i.e. without injection of contrast medium) allows, thanks to recent technological improvement of the spatial resolution, measuring several perfusion parameter of the retinal tissue such as the regional Blood Flow (rBF) or the cerebral blood flow (cBF) expressed in ml/100g/min. Reliable application of ASL thus requires the precision and specificity of the MRI protocol to be tested.
