Abstract：Objective To evaluate the value of transcranial Dopler ultrasound quantification in the analysis of intracranial blood flow for the patients with ischemic stroke.Methods 90 patients with ischemic stroke were selected as the observation group and 60 normal people as the control group.All cases were examined by color Doppler ultrasound,and the related indexes of intracranial blood flow parameters were detected,peak systolic velocity(PSV),end diastolic velocity(EDV),mean flow ve-locity(MV),resistance index(RI)and pulsatility index(PI)were measured.Results PSV,EDV and MV in the observation group were(62.60±7.96)cm/s,(27.38±4.29)cm/s and(41.08±6.14)cm/s,lower than those in the control group(88.54±7.35)cm/s,(35.07±4.74)cm/s and(67.84±6.51)cm/s(P<0.05).RI and PI in the observation group were(0.63±0.13)%and(0.78±0.12)%,higher than the control group(0.52±0.11)%and(0.69±0.10)%(P<0.05).Conclusion Transcranial Dopler ultrasound scan of an ischemic stroke patient shows low blood flow in the intracranial artery and increased vascular resis-tance,which can provide reference for clinical diagnosis of stroke.
