OBJECTIVE: The purpose of this study was to assess the intraobserver and interobserver reproducibility of 3-dimensional (3D) power Doppler angiography-derived vascular indices in evaluation of vascularized solid and cystic-solid adnexal masses. METHODS: Stored 3D power Doppler angiographic volume data from 12 consecutive women with a diagnosis of a complex adnexal mass (6 cystic-solid and 6 solid) evaluated and treated at our institution were retrieved from our database for analysis. Two examiners performed the calculations blinded to each other. Calculations were performed offline in a computer using Virtual Organ Computer-Aided Analysis software (plane A, 9 degrees rotation step) to assess volume and vascularization (vascularization index, flow index, and vascularization-flow index) from solid areas within the tumor. In all cases, a definitive histologic diagnosis was obtained. Intraobserver and interobserver reproducibility was assessed by calculating the intraclass and interclass correlation coefficients for each index. RESULTS: All tumors proved to be malignant after surgical removal. Intraobserver reproducibility for both examiners and interobserver reproducibility were high for all indices (interclass correlation coefficient > 0.95). CONCLUSIONS: Three-dimensional power Doppler angiography is a reproducible technique for offline assessment of stored 3D volume data of vascularized adnexal masses. |
