Contras-enhanced ultrasound features of ovarian tumor torsion / 中华超声影像学杂志

ABSTRACT

Objective To investigate the contrast enhanced ultrasound(CEUS)features of ovarian tumor torsion(OTT).Methods Seventeen cases with OTT were evaluated using CEUS.CEUS was performed with low mechanical index and the contrast agent of Sono Vue.Results Thirteen cases with total torsion of ovarian tumor appeared as no enhancement.Four cases with partial torsion showecl hyperechoic enhancement in the early phase and hypoechogenicity in the late phase.Conclusions The enhancement of OTT has characteristic,which would be helpful for the diagnosis and differential diagnosis of OTT.
