摘要: BACKGROUND AND PURPOSE: From the time-attenuation curves of DSA flow parameters, maximal intensity, slope, and full width at half maximum selected vascular points are defined. The study explores reliability defining parameters by DSA. MATERIALS METHODS: Seventy patients with unilateral carotid artery stenosis (group A) 56 healthy controls B) were retrospectively enrolled. Fixed contrast injection protocols acquisition used all patients. M1, sigmoid sinus, internal jugular vein on anteroposterior view M2, parietal vein, superior sagittal sinus lateral chosen as ROI targets for measuring parameters. difference time intensity between 2 target was defined circulation points. RESULTS: from ICA to significantly longer in group A than B. slope lower M1 M2 larger demonstrated best diagnostic performance. CONCLUSIONS: derived can be a definitive alternative parameter intracranial measurement. Maximal complement characteristics subjects stenosis.
