Abstract:
2, but precise estimation of stenoses was impossible on CDUS. The stenosis degree and the length of stenosis measured by contrast-enhanced harmonic gray scale imaging were correlated well with those of DSA(r= 0.94 and 0.63 , respectively). Conclusions Microbubbles fill the arterial lumen with echoes at contrast-enhanced harmonic gray scale imaging. The ability to visualize the inner and outer surfaces of the vascular wall improved the evaluation of luminal abnormalities.
