“…In recent years, 3-D ultrasound has been used to identify major structures within the fetal brain that are not typically visualized using a conventional 2-D/axial approach [4,18,22]. Several studies have shown that selected 3-D volume datasets contain enough anatomic information to evaluate fetal brain anatomy in all three orthogonal planes [2-4, 14, 15, 18, 23].…”

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.

“…The use of 3D multiplanar navigation and VCI-C techniques to obtain reconstructed mid-sagittal views has been consensually reported as very successful, with rates ranging from 84% [10] , 88% [8] to 93-99% [13] . Our success rate in obtaining reconstructed mid-sagittal views with CC diagnostic-quality imaging from volumes acquired in axial planes was within these values.…”

Objective: To compare the feasibility and reproducibility of transvaginal and transabdominal approaches, and 3D volume reconstruction sonography for measurement of corpus callosum (CC) length at different gestational ages. Methods: Forty-six normal fetuses were examined by 2D and 3D ultrasound at 23-25, 27-28 and 31-32 weeks of gestation. Direct mid-sagittal views were obtained by either a transabdominal and/or transvaginal approach. 3D reconstructed mid-sagittal views were obtained by 3D multiplanar manipulations and Volume Contrast Imaging in the C-plane technique (VCI-C) from volumes acquired in axial planes. Results: The CC could be measured in 91% of transvaginal acquisitions, in 52% of transabdominal acquisitions, in 92% of multiplanar reconstructions, and in 86% of VCI-C reconstructions. The success rate was independent of gestational age for transvaginal acquisition and slightly dependent on gestational age for 3D reconstruction techniques. Transabdominal acquisition was dependent on gestational age and fetal presentation. Inter- and intra-observer agreement was slightly better for measurements obtained from direct mid-sagittal views with either transvaginal or transabdominal acquisition than in views obtained by volume reconstruction. The reproducibility of measurements taken in reconstructed mid-sagittal views decreased with gestational age. Conclusion: 3D volume reconstruction techniques allow visualization and measurement of the CC in a high percentage of cases, with good reproducibility.

“…Viñals et al (2007) reported that the midsagittal plane was easily obtained in all cases, with diagnostic-quality images of the corpus callosum acquired in 93.1% and 99.0% of cases by two examiners, respectively. Bornstein et al (2010a) performed off-line analysis using a transabdominal 3-D gray-scale and power Doppler volumes of the fetal brain acquired in 102 consecutive normal fetuses at 20 to 23 wk. Miguelote et al (2012) compared the feasibility and reproducibility of 3-D volume reconstruction ultrasound when used for measuring corpus callosum length in 46 normal fetuses examined by 2-DUS and 3-DUS at 23 to 32 wk of gestation.…”
