Since the introduction of sonography into clinical practice, two-dimensional ultrasound (2DUS) has represented the standard application in obstetrics care. Nonetheless, technological advancement has brought to healthcare givers a new opportunity that is three-dimensional ultrasound (3DUS). Are there nowadays convincing evidence that 3DUS offer advantages over 2DUS and have gained recognized as well as well established role to justify its inclusion into routine obstetrics practice? The technological advancement reached by 3DUS warrant appropriate operator training program in order to acquire expertise to manage ultrasound applications and software. When this "goal" is reached, there is no doubt concerning the fact that one of the main advantages of 3DUS over 2DUS is represented by anatomic acquisition of a volume. Once a volume data set has been acquired, it can be sectioned on-line or transferred to an external personal computer for post-processing analysis. At this stage, "navigation" within the volume is possible, and operators can then freely sectioned or rendered the volume on-demand. This is of dramatic importance in teaching and training clinical setting. Furthermore, volume can be acquired on standardized plane at remote site even by inexperienced operator in 3DUS and send for expert consultation using telemedicine. Although stored volume data sets are large, up to 10 megabyte, they can be compressed to about 15 to 20% of the original file size and submitted via Digital Imaging and Communications in Medicine (DICOM) technology for off-line consultation without noticeable loss of details or image quality 1 . Moreover, volume data sets can be shared by expert on dedicated website and be used in multicenter studies while demonstrating a high sensitivity and reliability 2,3 . 3DUS with its applications allow operators a simultaneous and less time consuming (when compared with 2DUS) rendering of the anatomical landmarks in three orthogonal planes when using the multiplanar mode. In such case, the region of interest is displayed on the upper left quadrant on the ultrasound video equipment while the sagittal plane, the coronal and the axial are rendered in plane A, plane B and plane C, respectively. The planes obtained from the 3D volume are parallel and not oblique or at an angle, as is the case with conventional 2DUS. In addition, when comparing 2DUS vs. 3DUS studies of pathological cases, one of the most important advantages offered by "navigating" inside the volumes generated by 3DUS is the ability to follow the green "reference" dot that indicates the

“…Several studies have reported that a single 3-D volume dataset acquired transabdominally in an axial plane allows detailed multiplanar examination of the fetal CNS in all three orthogonal planes [17,23,27,28]. Using this technique, clear differentiation between the CC and cavum septi pellucidi is limited due to the resolution in the reconstructed planes [12,14,15,19].…”

Objectives: To determine which 3-D techniques are most effective for “real time” prenatal ultrasound assessment of the corpus callosum and cerebellar vermis. Methods: A prospective study involving 100 consecutive normal singleton pregnancies attending routine anomaly scan at 19-23 weeks' gestation. Midsagittal structures of the fetal brain were assessed using six different methods of 3-D image acquisition and three post-processing techniques. The quality of the resulting images were then assessed and scored by a second operator. The significance of the difference between various techniques was assessed using the Friedman test. Results: The best method for visualization of both corpus callosum and cerebellar vermis in one image involved 3-D acquisition in a sagittal plane through the sagittal suture with manipulated 3-D OVIX™ (Oblique View eXtended Imaging) reconstruction. Five other methods scored closely and were not significantly different; all were based on 3-D acquisition in the sagittal plane through either sagittal suture or anterior fontanel. Conclusions: We have applied described techniques for 3-D central nervous system volume acquisition and have shown that the best method of assessment, allowing assessment of both the corpus callosum and the cerebellar vermis, involves midsagittal acquisition through the sagittal suture with 3-D OVIX reconstruction. This technique can be applied successfully in 83% of cases.

“…In addition, when 3-DUS technology is used, the volume can be stored, compressed and then sent to a remote site for expert consultation for post-processing analysis that has been found to be accurate (Bornstein et al 2010b;Rizzo et al 2011c;Salman et al 2011). Very recently, Passos et al (2014) established reference ranges for fetal cisterna magna length and area by 3-DUS in the multiplanar mode in 224 normal pregnancies between 17 and 30 wk of gestation.…”
