Value of vascular enhancement technology in diagnosis of fetal pulmonary sequestration / 中国介入影像与治疗学

ABSTRACT

Objective To assess the clinical value of vascular enhancement technology (VET) in diagnosis of fetal pulmonary sequestration (PS).Methods Color Doppler velocity (CDV),color Doppler energy (CDE) and VET were performed in 11 fetus with PS to display the vessels in region of interest.Results The abnormal vessels in region of interest were displayed in distinct degree with CDV,CDE and VET.The courser and disposition of the great vessels were displayed with CDV and CDE,while lumen of blood vessel was clearly discriminated with VET,while CDV depicted the direction of blood flow.Satisfaction assessment of the VET image was superior than those of CDV and CDE image (P0.05).Conclusion VET can improve the contrast resolution,having superiority in displaying vessels and fine branches,therefore has clinical value in the diagnosis of fetal PS.
