“…Only an experienced sonologist could acquire the volumes of interest, whereas other sonologists less experienced would be able to process them offline with completely reliable results. Raine-Fenning et al 6,7 also showed high intraobserver and interobserver reproducibility of ovarian 3D-PDA indices. The Intra-CC and, particularly, Inter-CC were not as high as those of Jarvela et al 5 These authors observed an FI Inter-CC of just 0.29 in 22 ovaries after 8 days with controlled stimulation treatment.…”

“…In general, the mean ovarian volume is more reproducible after ovarian stimulation, whereas Doppler indices are more reproducible in the basal ovary after pituitary suppression. Jarvela et al 5 and Raine-Fenning et al 6,7 recently evaluated intraobserver and interobserver repeatability of the ovarian volume by the rotational method. In accordance with our findings, both groups observed excellent reproducibility, with Intra-CC and Inter-CC very close to 1.…”

“…1 The volume measurement by 3D ultrasonography is more reliable than that obtained by 2-dimensional ultrasonography. 2,3 The ovarian volume calculated from serial multiple slices 4 or, more recently, from a rotational method using the Virtual Organ Computer-Aided Analysis (VOCAL) imaging program [5][6][7] has very good reproducibility. Good reproducibility of the antral follicle count has also been shown by means of this technique.…”

“…6 It has been shown that the 3D power Doppler indices are reproducible enough to evaluate the ovarian blood flow, although some differences are observed in relation to the applied methods. [5][6][7] In fact, Jarvela et al 5 used an angle of 30°to measure the ovarian volumes and vascularity indices, which shows the poorest reproducibility.…”

Objectives. The purpose of this study was to assess intraobserver and interobserver reproducibility of the parameters of ovarian response and oocyte ability, studied by 3-dimensional ultrasonography and power Doppler angiography (PDA), and the possible influence of the ovarian functional stage. Methods. Twenty-nine women were included in an in vitro fertilization program. Fourteen women were evaluated after pituitary suppression (basal group), and 15 were scanned on the human chorionic gonadotropin administration day, after gonadotropin ovarian stimulation (stimulated group). A first observer acquired 2 volumes for each ovary. Another observer performed a second analysis of the volumes acquired by the first observer. We analyzed ovarian volume, follicle number in the basal group, vascularization index, flow index, and vascularization-flow index. The volumes were processed by the Virtual Organ Computer-Aided Analysis imaging program using plane A and 15°rotational steps. Results. Ovarian volume showed excellent intraobserver and interobserver agreement, with an intraclass correlation coefficient (Intra-CC) and an interclass correlation coefficient (Inter-CC) close to the unit. The Intra-CC and Inter-CC about the number of follicles were 0.964 and 0.978, respectively. Vascularity indices showed an Intra-CC greater than 0.90. The vascularization index and the vascularization-flow index showed higher interobserver than intraobserver reproducibility (Inter-CC > 0.96 for both). The flow index Inter-CC was 0.898. The reproducibility differences between the basal and stimulated ovary measurements were not significant. Conclusions. There is an excellent intraobserver and interobserver reproducibility of the ovarian volume, follicle counts, and 3-dimensional PDA indices. The ovarian functional stage has no influence on the reliability. Three-dimensional ultrasonography and PDA improve the study of ovarian parameters, and their reliability impels a change in the current clinical routine of performing and interpreting ultrasonography.

Purpose:The purpose of this study was to compare the intra-observer and inter-observer agreement in assigning a diagnosis of malignancy or benignity to adnexal masses using 2-dimensional ultrasonography (2D US) and 3-dimensional ultrasonography (3D US). Methods:Two experienced observers (Observers A and B) performed a retrospective review of digitally stored 2D images and 3D data from a sample of 41 consecutive patients with a diagnosis of adnexal mass. Each observer independently, and blinded each other, evaluated the 2D static images of each adnexal mass and then the 3D volumes one-week later. The observers were required to classify the adnexal lesion as benign or malignant according to pattern recognition analysis. Intra-observer and inter-observer agreement were assessed by calculating the kappa index (κ). Results:Intra-observer agreement between 2DUS and 3DUS for the observer A was 1.00 and for the observer B was 0.69. Inter-observer agreement was 0.69 for 2D US and 1.00 for 3D US (p >0.05)Intra-observer agreement between 2DUS and 3DUS for the observer A was 0.96 and for the observer B was 0.77. Inter-observer agreement was 0.73 for 2D US and 0.92 for 3D US Conclusions:Our results indicate that 3D US for assessing adnexal masses is reproducible, but not significantly, than 2D USOur results indicate that 3D US for assessing adnexal masses is reproducible, even more than 2D US.Running Head: Three and Two-dimensional ultrasound: intra-inter-observer agreement
