 Abstract: Tracking a bolus of contrast agent traveling through the cerebral vasculature provides a measure of the blood supply and the blood flow velocity in the respective cerebral tissue. This principle has been the basis for the first approaches in functional MR imaging and is of great value when investigating stroke and other vascularly compromised patients. While the bolus measurement is a standard procedure in clinical MR imaging, optical bolus tracking has not yet become a reliable protocol. Here optical absorption changes induced by bolus signals of the dye indocyanine- green are studied by near infrared spectroscopy on volunteers. The aim is to assess the latency and shape of the absorption change.
