3D ultrasound technology makes it easier than ever to diagnose uterine malformations. This is why it has become the gold standard in gynecological imaging tools. "It is the first true great revolution in ultrasound," says Brunella Zizolfi, PhD in Neuroscience at the University of Naples Federico II. "It provides precise information on both the external and internal morphology of the uterus." This cutting-edge imaging modality is proving to be a transformative force in gynecology, bringing diagnostic precision and patient care to new heights.

The ability to unravel the intricate anatomical detail of the female reproductive system with unparalleled precision is a key advantage of 3D ultrasound. The comprehensive views provided by 3D ultrasound can lead to more informed diagnoses in gynecology. This innovative gynecological tool simplifies complex examinations, including identifying uterine malformations. With 3D technology, more visually informative scans also enhance doctor and patient communication.
3D ultrasound enhances gynecologists' ability to detect abnormalities of the uterus, facilitating early intervention and improving patient outcomes. The detailed anatomical visualization afforded by 3D imaging assists in more accurate diagnoses, prompting a deeper understanding of complex pathologies. 3D ultrasound allows for clearer communication and patient education, significantly enhancing the patient experience.
Introduction to the Uterine Trace Tool and Its Primary Functions
The Uterine Trace tool integrates with 3D ultrasound technology to enhance consistency and accuracy in gynecological diagnosis. It is an intuitive touchscreen gynecological tool that provides both volume and precise measurement that coordinate with uterine classification guidelines to yield the right diagnosis of uterine malformations.
Always begin with a 2D scan when using the Uterine Trace tool. The 2D scan provides information about the position, size, and echotexture of the uterus. Echotexture is evaluated from fundus to cervix in both the sagittal and transverse planes but does not offer the full picture of the uterine shape and cavity.
The Uterine Trace tool creates its 3D image by acquiring an ultrasound volume. First, it is important to optimize the 2D image to obtain a clear 3D image. Optimization is necessary if the image has shadows or is poorly defined, particularly regarding the area of interest. Reduce box size to observe only the uterus, fundus to cervix.
To acquire volume, multiple 2D images are added together as the ultrasound beam sweeps through the area of interest. The uterus is a curvilinear organ best visualized with a curvilinear tool. With the Uterine Trace tool, the practitioner simply traces a line with their finger on the screen to follow the contour of the endometrial cavity and cervical canal. Acquisition of volume allows an accurate evaluation of the entire uterine cavity.

3D gynecological imaging is often thought of as surface-rendered images, but it also involves the multiplanar reconstruction of three orthogonal planes:
- The A(X) plane displays the 2D image plane in which the volume was acquired and provides highest resolution
- The B(Y) plane is perpendicular to the X plane with a vertical orientation
- The C(Z) plane is perpendicular to the X plane with a horizontal orientation—this is the coronal plane and cannot be obtained in 2D imaging
Optimizing the Image
Using the touchscreen, in the A plane place a dot or reference point in the center of the endometrium. Then rotate to align the long axis of the endometrium with the horizontal (X) plane. Then move to the B plane and position the dot in the center of the endometrium. Rotate, aligning the endometrial axis along the horizontal (Z) plane. Optimize the coronal plane view by placing the dot in the center to clearly visualize both cornua and the cervix. Activating Volume Contrast Imaging (VCI) can improve image quality. This feature increases contrast resolution and reduces artifacts, particularly helpful when evaluating the junctional zone.
Integration with ASRM, ESHRE, and ESGE Uterine Classification Guidelines
Uterine Classification
The Uterine Trace tool links with ASRM, ESHRE, and ESGE Uterine Classification guidelines. These classification systems have defined measurement techniques, reference points, and specific cut-offs to differentiate between normal and septate uteri and other uterine malformations. Accurate measurements are key to differential diagnosis, and a seamless link from gynecological tools to the guidelines allows for automated classifications. Different guidelines result in different rates of diagnosis of various uterine malformations. For example, the ESHRE/ESGE Uterine Classification guidelines result in significantly more diagnoses of septate uteri compared to the ASRM guidelines.

Advancements in Gynecological Tools Lead to Better Diagnoses
3D ultrasound technology streamlines both identification and reporting of uterine malformations. The amount of information that can be visualized allows for consistency and accuracy in gynecological diagnosis. The dynamic nature of 3D ultrasound extends beyond mere visualization. This tool can help provide a comprehensive understanding of complex pathologies.
Additional gynecological tools further enhance 3D ultrasound by streamlining the way physicians interact with the technology. For example, with the Uterine Trace tool, gynecologists now have a far more user-friendly approach to acquire volume and make accurate measurements when utilizing 3D ultrasound technology to visualize the female reproductive system. "I think this could be a game changer," says Ralf Menkaus, MD, of Germany's Center for Fertility Treatment and Prenatal Diagnosis Minden. "We do a 3D ultrasound of the uterus in every patient to identify malformations or rule out myomas." Now those scans are enhanced by the use of the Uterine Trace tool.
