AB SUMMARY: Time-density curve analysis of DSA provides useful blood flow information. However, manually selecting the ROI is time-consuming. We developed an automatic technique to provide arterial, capillary, and venous vasculatures with corresponding time-density curves. This study retrospectively analyzed the data of 36 patients with unilateral carotid stenosis. We found that the full width at half maximum of the time-density curve for the automatically segmented capillary vasculature is a suitable representation of the cerebral circulation time.CCTcerebral circulation timeFWHMfull width at half maximumI1 and I2the internal carotid artery at 2 locationsIAcervical internal carotid artery in the lateral viewIBcavernous segment of the internal carotid artery in the lateral viewMCPmanually selected capillary phasePAposteroanteriorTDCtime-density curve
