Abstract:
Objective To explore the utility of super micro-vascular imaging (SMI) and color Doppler flow imaging (CDFI), in combination with the use of gynecologic imaging reporting and data system (GI-RADS), in evaluating benign and malignant ovarian tumors.
Methods A total of 168 patients with ovarian tumors in Langfang People’s Hospital, between September 2019 and March 2021, were included in the study. Fifty-six were included in the malignant group, and 112 were included in the benign group. Tumor blood flow was observed via SMI and CDFI. SMI with GI-RADS and CDFI with GI-RADS were used to predict the tumor nature. The postoperative pathological diagnosis was considered gold standard.
Results In the malignant group, blood flow abundance detected using SMI was significantly higher than that detected using CDFI (P<0.05). However, no significant difference in blood flow abundance was observed between SMI and CDFI in the benign group (P>0.05). The number of malignant ovarian tumors diagnosed using CDFI with GI-RADS and SMI with GI-RADS was 53 and 55, respectively. Both methods had a sensitivity rate of 94.6% and 98.2%, specificity of 93.8% and 95.5%, and accuracy of 94.0% and 96.4%, respectively. The results were consistent with the pathological results (κ=0.868 and κ=0.921).
Conclusions SMI with GI-RADS provided a better differential diagnostic efficacy for benign and malignant ovarian tumors. Moreover, this method provides higher sensitivity and specificity than CDFI with GI-RADS.
