“…16 Some researchers have evaluated the role of 3D sonography for discriminating between benign and malignant adnexal masses. Bonilla-Musoles and colleagues 5 and Kurjak and coworkers 6 found that 3D sonography was more sensitive than 2D sonography. Conversely, Hata and coworkers 7 found that 3D sonography was more specific than 2D sonography.…”

Objective. The purpose of this study was to assess the reproducibility of 3-dimensional (3D) sonography for classifying adnexal masses. Methods. Eighty-two consecutive women with the diagnosis of an adnexal mass on 2-dimensional transvaginal sonography were reevaluated by 3D sonography, and 3D volume data from each mass were stored. Two different examiners (6 years and 1 year of experience in 3D sonography, respectively) reviewed 3D sonograms 1 month after the last patient was recruited and then 1 week later again. Masses had to be classified as benign or malignant. Criteria suggestive of malignancy were the presence of a thick wall, gross papillary projections, solid areas, and solid echogenicity. A definitive histologic diagnosis was obtained in every case. Intraobserver and interobserver agreement was estimated by calculating the Cohen κ index. Results. Twenty-seven (33%) tumors were malignant, and 55 (67%) were benign. Intraobserver agreement for both examiners was good (κ = 0.78 and 0.72, respectively). Interobserver agreement was also good (κ = 0.70). Conclusions. Three-dimensional sonography is a reproducible technique for morphologic assessment of adnexal masses. Key words: ovarian tumor; reproducibility; sonography; 3-dimensional sonography.Received March 27, 2007, Recently, 3-dimensional (3D) sonography has been introduced in clinical practice. This technique overcomes some limitations of conventional 2D sonography, allowing a more detailed assessment of morphologic features of the object studied, with no restriction to the number and orientation of the scanning plane.4 Several studies have evaluated the role of 3D transvaginal sonography in assessing adnexal masses, reporting controversial results. 5-8The issue of reproducibility is essential when proposing a new technique to be introduced into clinical practice.

“…13 More recently, evidence has become available showing the advantages of 3D sonography in gynecology. In these studies, 3D sonography allowed improved classification of ovarian tumors 14 as well as improved evaluation of the postmenopausal endometrium. 15,16 Finally, 3D sonography was highly accurate in the diagnosis of müllerian anomalies.…”

Objective. To evaluate the clinical relevance of 3-dimensional saline infusion sonography (3D-SIS) in addition to conventional SIS in women with abnormal uterine bleeding suspected of having intrauterine abnormalities. Methods. All women suspected of having intrauterine abnormalities were eligible. Before 3D-SIS, conventional SIS was performed. The results of these techniques were compared with the "combined method reference standard" (hysteroscopy, endometrial sampling, and clinical followup in cases with normal SIS findings). Diagnostic characteristics (with 95% confidence intervals [CIs]) of 3D-SIS and SIS were calculated as well as their respective accuracy in evaluating the histologic nature, the intrauterine extension, and the location of intrauterine abnormalities. Moreover, the reliability (κ value) and clinical relevance of 3D-SIS were assessed. Results. A total of 49 women were included, and 4 women were excluded. The positive predictive values of 3D-SIS and SIS were, respectively, 1.00 and 0.86 (95% CI, 0.72-0.99; P = .15), and the diagnostic accuracy values were 0.98 (95% CI, 0.94-1.0) and 0.91 (95% CI, 0.83-0.99; P = .08). Saline infusion sonography and 3D-SIS were equally accurate in evaluating the histologic nature, intrauterine extent, and location of intrauterine abnormalities (respective κ values: 0.85 versus 0.93; P = .88; 0.83 versus 0.83; and 0.77 versus 0.80; P = .81). The reliability of 3D-SIS was good: intraobserver and interobserver agreement (κ) were 0.78 and 0.72. Three women (6.7%) had the benefit of additional 3D-SIS: in these women, SIS wrongly led to a diagnosis of intrauterine abnormalities (P = .08). Conclusions. Three-dimensional saline infusion sonography is valid and reliable in women suspected of having intrauterine abnormalities and may indeed have relevant clinical value in addition to conventional SIS.

Abstract:The differential diagnosis of adnexal masses still constitutes a major clinical challenge. B-mode ultrasonography is the most used imaging technique and it is the base for this differential diagnosis with acceptable results in terms of sensitivity but a relatively high false positive rate for predicting ovarian cancer. The role of pulsed Doppler remains controversial and seems to be not reproducible in clinical practice. In the last years, a new technology such as 3D ultrasound-both morphology and 3D Angio power Doppler-has become available for discriminating between benign and malignant ovarian tumors. In this article I aim to review critically recent literature of this topic.
