Objective To explore the diagnostic value of aoustic radiation force impulse (ARFI) combined with superb micro vascular imaging (SMI) for ovarian cancer and its clinical staging. Methods A total of 74 patients with ovarian tumors undergoing radical surgery in Shiyan Taihe Hospital were enrolled between January 2021 and June 2023. All underwent ARFI and SMI examinations before surgery to measure shear wave velocity (SWV) and resistance index (RI) in the hardest lesion tissues. All patients underwent pathological examination of lesion tissues after surgery. According to the results of histopathological examination after radical surgery, were divided into ovarian cancer group and benign tumor group, general data, maximum tumor diameter, SWV and RI in the two groups were compared. The diagnostic efficiency of ARFI, SMI parameters and combined detection for ovarian cancer was analyzed by receiver operating characteristic (ROC) curves. SWV and RI in patients with different clinical staging of ovarian tumor were compared. Kappa consistency between ARFI, SMI and postoperative histopathological examination in the diagnosis of ovarian cancer staging was analyzed. Results Among the 74 patients with ovarian tumors, histopathological examination showed that there were 49 cases with ovarian cancer, including 9 cases with FIGO staging at stage I, 21 cases at stage II, 14 cases at stage III and 5 cases at stage IV. The maximum tumor diameter and SWV in ovarian cancer group were significantly higher than those in benign tumor group, while RI was significantly lower than that in benign tumor group (P<0.05). The results of ROC curves analysis showed that area under the curve (AUC) values of SWV and RI in the diagnosis of ovarian cancer were 0.832 and 0.815, and their sensitivities were 63.27% and 61.22% (P<0.05). AUC and sensitivity of SWV combined with RI in the diagnosis of ovarian cancer were 0.887 and 77.55%, better than those of single index (P<0.05). There were significant differences in SWV and RI among ovarian cancer patients with different clinical staging. SWV and RI were higher in patients with high clinical staging (P<0.05). Taking the results of pathological examination as the golden standard, accuracy and Kappa values of ARFI and SMI in the diagnosis of ovarian cancer staging were (81.63%, 75.51%) and (0.732, 0.642), respectively (P<0.05). Conclusion ARFI combined with SMI can improve diagnostic efficiency for ovarian cancer. The diagnostic efficiency of ARFI is superior to SMI in terms of ovarian cancer staging.
