Fig. 2From: Cerebral arterial flow dynamics during systole and diastole phases in young and older healthy adultsExample of flow quantification of the left internal carotid artery at the intracranial level using the “Flow” software. The software performs a semi-automatic segmentation and calculates the ROI area and the fluid velocity over the cardiac cycle. Subsequently, the software extracts the average flow waveform from the selected vesselBack to article page
