RESUMO
Objective To investigate the application of real-time gray-scale contrast enhanced ultrasound (CEUS)imaging in the diagnosis of fallopian tube obstruction.Methods Forty-six females with infertility in the period of 3-7 days after menses were inspected by transvaginal CEUS,and the transmission of contrast agents in the fallopian tubes was observed.Then they were inspected by routine iodic X-ray salpingography.Later the value of real-time gray-scale CEUS in diagnosis of fallopian tube was evaluated.Results The sensitivity of CEUS indiagnosis of fallopian tubal unobstruction,obstruction and open without freely was 92.0%,87.1%,36.4%respectively;the specificity was 85.7%,96.7%,93.7%;the accurate was 89.1%,93.5%,84.7%;the Kappa was 0.78,0.85,0.16 with X-ray salpingography.The concordance was 83.7% between CEUS and X-ray salpingography.Conclusions There were no significant difference between CEUS and X-ray salpingography in diagnosis of fallopian tube unobstruction or obstruction,and the former method is safer and more convenient that is suitable to become an valuable method in inspecting of infertility.
