Abstract:
Objective To evaluate the accuracies of two-dimensional ultrasound(2D-US)and three-dimensional ultrasound virtual organ computer-aided analysis(3D-VOCAL)in measuring uterine myoma volume(UMV).Methods Forty-five patients who underwent surgical treatment for uterine myoma at Longyan First Hospital,Fujian Medical University from October 2022 to April 2023 were selected.Preoperative measurements of UMV were performed using 2D-US and 3D-VOCAL,and the measurement results were compared with the actual UMV after surgical resection to assess the accuracies and repeatabilities of the two ultrasound techniques in measuring UMV.Results The UMV measurement consistency of 3D-VOCAL(ICC=0.992)was higher than that of 2D-US(ICC=0.976),and the ICC values of 3D-VOCAL were higher than those of 2D-US in UM of different sizes(all P<0.001).Statistically significant differences among 2D-US,3D-VOCAL and postoperative measurement results was found in UM with a maximum diameter≥8 cm(P<0.05),but not in UMV and UM with a maximum diameter<8 cm(P>0.05),and the further analysis showed that in UM with a maximum diameter≥8 cm,the UMV measured by 2D-US differed from postoperative measurement results(P<0.05).The differences between 3D-VOCAL measurement results and postoperative measurement results were trivial(P>0.05).There were greater intra-and interobserver agreements by 3D-VOCAL than 2D-US in UMV measurement.Conclusion 3D-VOCAL which is superior to 2D-US in preoperative UMV measurement is a simple,efficient,and reliable method,and it can provide theoretical bases for clinical follow-up.
