Diagnostic Efficiency of Gynecologic Imaging Reporting and Data System Combined With 3-dimensional Contrast-enhanced Ultrasound Scoring System in Evaluating Ovarian Tumor

To estimate the value of gynecologic imaging reporting and data system (GI-RADS) combined with 3-dimensional contrast-enhanced ultrasound (3D-CEUS) scoring system in the differential diagnosis of ovarian tumor. Both of 2-dimensional ultrasound (2D-US) and 3D-CEUS were performed on 114 patients with ovarian masses by Voluson E8 with SonoVue (Bracco, Italy). Besides, dynamic contrast-enhanced-magnetic resonance imaging (DCE-MRI) (Siemens Magneton Verio 3.0T, Germany) was performed on the patients. There were totally 62 benign and 52 malignant ovarian tumors in all patients. The ability of GI-RADS combined with 3D-CEUS scoring system to distinguish benign and malignant ovarian tumors was superior to conventional ultrasound GI-RADS classification. The sensitivity, specificity, and accuracy of GI-RADS combined with 3D-CEUS scoring system were 96.2% and 98.1%, 87.10%, whereas those of MRI were 87.10%, 91.23%, and 92.11% respectively, indicating that there was high concordance in ovarian tumors assessment between the 2 diagnostic methods. The new scoring system has a good correlation with microvessel density (P = 0.000, r = 0.73), estrogen receptor (P = 0.000, r = 0.59), progesterone receptor (P = 0.000, r = 0.56), and matrix metalloproteinase-9 (P = 0.000, r = 0.61). The GI-RADS combined with 3D-CEUS scoring system was valuable in clinical diagnosis and differential diagnosis of ovarian tumor and show good agreement with MRI.
