Objective To investigate the diagnostic value and guiding significance of shear wave combined with strain ultrasound elastography(SE)in hemorrhagic ovarian cyst and endometriosis.Methods A total of 126 patients with pelvic masses in Chengde Central Hospital from January 2019 to May 2021 were selected as the research group,and 63 healthy women who underwent physical examination during the same period were selected as the control group.All patients underwent shear wave ultrasound elastography(SWE)and SE examination,compared the shear wave velocity(SWV),the mean value(Emean),the maximum value(Emax)and the minimum value(Emin)of elastic modulus and the strain rate ratio(SR)between the two groups.According to the pathological examination results,the research group were divided into the endometriosis subgroup(60 cases),hemorrhagic ovarian cyst(66 cases)as the ovarian cyst subgroup,and analyzed the value of SWE combined with SE in the diagnosis of hemorrhagic ovarian cyst and endometriosis.Results SWV,Emean,Emax,Emin and SR in the research group were higher than those in the control group(P<0.05);SWV,Emean,Emax,Emin and SR in the endometriosis subgroup were higher than those in the ovarian cyst subgroup(P<0.05);SWE imaging manifestations:compared with hemorrhagic ovarian cysts,endometriosis had a faster SWV and higher elasticity value;SE imaging manifestations:The color coding of endometriosis strains was mainly red or orange-red,and the strain type mainly type 3,with high SR value;color coding of hemorrhagic ovarian cysts was mainly green or yellow-green,and a few were blue or blue-green and red or orange-red,strain types are concentrated in type 2,and SR was relatively low;Pearson correlation analysis showed that SR was positively correlated with SWV,Emean,Emax and Emin(P<0.05);according to ROC curve analysis,the AUC of the combined diagnosis of SWV,Emean,Emax,Emin and SR was 0.924(95% CI:0.863-0.964),with a sensitivity of 90.00% and a specificity of 86.36%,which was significantly better than that of each parameter alone.Conclusion SWE combined with SE examination has high diagnostic value in hemorrhagic ovarian cyst and endometriosis,and can provide reliable guidance information for clinical diagnosis and treatment.
