Type II ovarian epithelial cancer is the most lethal type of ovarian cancer that originates in the non-ciliated portion of the distal fallopian tube and spreads into the ovary. Our study focuses on improving the sonographic depiction of the distal fallopian tube (DFT) using 3D contrast-enhanced sonosalpingography (3D CE-SSG).
This IRB-approved prospective study enrolled a total of 8 BRCA+ women undergoing risk reduction salpingography using a Philips 3D93-3v probe attached to an Epic 7 scanner (Philips Healthcare, Bothell, WA). The volumetric data was obtained and post-processed using Qlab, MATLAB, and 3Dslicer software. The outer surface and lumen of the DFT were further evaluated qualitatively and quantitatively.
Our preliminary results demonstrate an impressive success rate in accurately depicting the volumetric and luminal characteristics of the DFT, which may be the sensitive findings for type II ovarian epithelial cancer. Through detailed sectioning and the innovative fimbriated end protocol, we offer unique insights into the gross and microscopic appearance of the fallopian tube.
Join us in exploring the pioneering technique's ability to depict the volumetric and luminal anatomy of the DFT. This work opens the door to a potential advancement in the early detection of Type II ovarian epithelial cancer using 3D-contrast-enhanced ultrasound.
