OP24.10: GI-RADS: a new proposal for classifying adnexal masses based on sonographic findings

S-BOT (p = 0.05). M-BOT had echogenic fluid more than S-BOT, but this difference did not reach statistical significance. Only in 5/11 tumors (45%) a significant blood flow was documented. 11/23 (47%) tumors were correctly triaged for oncology-related surgery procedure based on clinical and sonographic evaluation. Conclusions: Echogenic fluid, multilocularity and a larger diameter is more typical to M-BOT. Papillary projections are more often associated with S-BOT. Correct triage for an oncology-related surgery, based on these factors, seem less successful than expected.
