CVI may yield more consistent flow estimates than SDI in healthy subjects; hypothesis-generating for cerebrovascular applications, requires prospective validation.
Does color velocity imaging (CVI) improve the accuracy of blood flow volume estimation compared to spectral Doppler imaging (SDI) in healthy subjects?
Color velocity imaging is significantly more accurate than spectral Doppler imaging for the noninvasive estimation of cerebrovascular blood flow volume.
