Gynecological tumors are a frequent clinical problem. Accurate diagnosis is essential for an adequate clinical management. Currently, 2D ultrasound is considered as a first line imaging technique for diagnosis and for discriminating benign from malignant lesions. However, some limitations of this technique exist. Three-dimensional is a relatively new technique that allows some unique ways for assessing gynecological tumors by ultrasound. In this article, I shall review current evidence about the use of three-dimensional ultrasound for assessing gynecological tumors.

“…It is believed that vascularization index (VI) represents the amount of vessel in the examined volume, flow index (FI) shows the flow intensity, and vascularization-flow index (VFI) reflects the combination of both [27]. A number of studies examined the suspicious areas in adnexal masses and found that 3D PD indices were significantly higher in those that are malignant [29][30][31][32]. It is worth mentioning that there is no agreement among experts on which specific index is better at diagnosing malignancies, or which cut-off value provides the best sensitivity and specificity.…”

Three-dimensional ultrasound (3D USG) is a fast-evolving imaging technique that holds a great potential for use in gynecology. Its sensitivity and specificity is reported to be close to 100 % for diagnosing congenital uterine anomalies, comparable with those of magnetic resonance imaging (MRI) and laparoscopy. With 3D USG, a coronal view of the uterus can be obtained, clearly outlining the external contour of the uterus and providing accurate information about the shape of the cavity. Although 3D USG may not perform well in thin endometria, combining it with saline infusion sonography (SIS) overcomes this problem. Research shows that 3D USG is more sensitive and specific than two-dimensional ultrasound (2D USG) in defining and mapping uterine lesions, such as fibroids, adenomyosis, and intrauterine synechia. In cases of suspected malignancy, 3D USG is mainly used in the initial evaluation of patients. Measuring various indices and mapping vascular architecture with 3D power Doppler have been proposed for evaluating adnexal masses. Although some studies raised hope, no consensus is reached about its use, success, and limitations. In urogynecology, translabial 3D USG is proved to be a valuable tool, as it provides instant access to the axial plane, which clearly depicts the relationship of the vagina, urethra, rectum, and the muscular pelvic floor. Studies report no significant differences between translabial 3D USG and MRI measurements for evaluation of the pelvic floor. In conclusion, adding 3D USG to routine gynecological workup can be beneficial for clinicians, as it provides fast and accurate results in a relatively cost-effective setting.

Three-dimensional ultrasound is an imaging technique that is being introduced into clinical practice in several medical specialties. Although this technique is unlikely to replace the two-dimensional ultrasound, its role as a diagnostic tool is being explored. In fact, in the field of gynecology there has been a steady increase in the number of papers published in the last few years. These applications include: imaging the uterus, uterine cavity, adnexa, and pelvic floor as well as reproductive medicine, such as the prediction of IVF success or ovarian hyperstimulation syndrome. The aim of this paper is to review the current status of threedimensional ultrasound in clinical practice in gynecology.
