The advantage of using 3D ultrasound over 2D ultrasound lies in the enhanced visualization of structures and improved diagnostic accuracy.

3D ultrasound technology captures a series of 2D images from multiple angles and combines them into a three-dimensional representation. This method allows for a more comprehensive view of anatomical structures, enabling clinicians to better identify abnormalities, assess complex structures, and facilitate more accurate diagnoses. For instance, 3D ultrasound can provide clearer images of fetal anatomy during pregnancy, assisting in detecting congenital anomalies and aiding in surgical planning when necessary.

In contrast, the other options either relate to aspects not fundamentally linked to the core advantages of 3D imaging or are not accurate regarding ultrasound technology. While patient comfort, radiation exposure, and costs are important considerations in medical imaging, they do not specifically capture the distinct primary benefit of 3D ultrasound, which is its capacity for improved visualization and diagnostic precision.
