Abstract

Objective To evaluate the repeatability for location of the level of fetal conus medullaris (CM) with three-dimensional volume contrast imaging (3D-VCI). Methods Totally 164 normal fetuses and 12 fetuses with low-lying CM were enrolled. The location of fetal CM was performed sonographically using 3D-VCI, and the inter- and intra-observer agreement was assessed. Results The Kappa value of inter- and intra-observer agreement in evaluation on normal fetues CM was 0.943 and 0.915, and that for abnormal fetues CM was 0.965 and 0.913, respectively. Conclusion Inter- and intra-observer agreement of 3D-VCI in location of level of fetal CM is high. The acquired images are clear and intuitive, which is manipulated simply and conveniently.This method can be used for rapid evaluation of the level of fetal CM.
