“…Congenital conditions of facial and cervical structures that are associated with fetal growth, genetic diseases, fetal death, and upper airway obstruction, are associated with significant morbidity and may even be fatal 16,17 . Rapid advances in imaging and instrumentation technology combined with superior knowledge of fetal pathophysiology, have led to the development of novel intrapartum interventions for most common fetal anomalies [18][19][20] . Furthermore, the assessment of facio-cervical lesions in utero can have significant importance in obstetric management since masses in this anatomical space may change rapidly and obstruct the airway.…”

Congenital facio-cervical masses can be a developmental anomaly of cystic, solid, or vascular origin, and have an inseparable relationship with adverse prognosis. This retrospective cross-sectional study aimed at determining on the prenatal diagnosis of congenital facio-cervical masses, its management and outcome in a large tertiary referral center. We collected information on prenatal clinical data, pregnancy outcomes, survival information, and final diagnosis. Out of 130 cases of facio-cervical masses, a total of 119 cases of lymphatic malformations (LMs), 2 cases of teratoma, 2 cases of thyroglossal duct cyst, 4 cases of hemangioma, 1 case of congenital epulis, and 2 cases of dermoid cyst were reviewed. The accuracy of prenatal ultrasound was 93.85% (122/130). Observations of diameters using prenatal ultrasound revealed that the bigger the initial diameter is, the bigger the relative change during pregnancy. Magnetic resonance imaging (MRI) revealed that 2 cases of masses were associated with airway compression. In conclusion, ultrasound has a high overall diagnostic accuracy of fetal face and neck deformities. Prenatal US can enhance the management of ambulatory monitoring and classification. Furthermore, MRI provided a detailed assessment of fetal congenital malformations, as well as visualization of the trachea, presenting a multi-dimensional anatomical relationship.

“…Sonographers are aware of acoustic shadows that may worsen the quality of a brain volume and usually try to avoid these during the acquisition process. Some authors have made recommendations on both volume acquisition and processing, but these same recommendations have not always been evaluated in subsequent studies 5 …”

Introduction This study aimed to evaluate the quality of the brain volumes acquired following an evidence‐based guideline for the acquisition of brain volumes. Material and methods This was a prospective multicenter study. Five centers recruited five cases each, acquiring two volumes per case, at different gestational age ranges. From the collected volumes, 10 operators performed an advanced neurosonography of each case. The evaluable anatomic structures were counted in each volume and expressed as a percentage. The results were compared with those obtained in a previous study where no recommendations had been made for the acquisition of the volumes. Results Five hundred evaluations were included in the study. In the axial plane, 91.5% of the structures were satisfactorily evaluated, 81.8% in the coronal plane and 89.9% in the sagittal plane. These results were significantly better than those obtained in a previous study where the volumes had been acquired without any guidelines and the percentage of evaluable structures were 80% (P < .001), 67.1% (P < .001) and 55.1% (P < .001) in the axial, coronal and sagittal planes, respectively. Conclusions The application of an evidence‐based guideline for the acquisition of brain volumes improves the quality of these by increasing the number of evaluable structures in the volume.

“…Crystalvue is a context-preserving post-processing software for 3D volumes manufactured by Samsung Medison Co. Ltd (Seoul, Korea) that allows easier differentiation between tissues with different echogenicity by enhancing contrast and depicting subtle outline and texture [21]. Using Inversion mode, hyperechoic linear sulci on 2D gray-scale US image are changed to dark lines and hypoechoic gyri to bright convexity structure; therefore, the anatomic relationship between sulci and gyri can be clearly displayed similar as brain specimen.…”

Purposes: To demonstrate sulci and gyri morphological alteration on convex surface in normal fetus using an innovative three-dimensional inversion and Crystalvue and Realisticvue (3D-ICRV) rendering technology. Materials and Methods: 3D fetal brain volumes were collected from low risk singleton pregnancies between 15+0 and 35+6 gestational weeks. Volumes were acquired from transthalamic axial plane by transabdominal ultrasonography, which were then post-processed with Crystalvue, Realisticvue rendering software and inversion mode. Volumes quality were assessed. The anatomic definition of the sulci and gyri were determined according to its location and orientation. The morphology alteration and sulcus display rates were recorded in sequential gestational weeks order. Follow up data were collected in all cases. Results: Of 300 fetuses, 294 fetuses (294 brain volumes)(98%)with qualified fetal brain volumes were included (n=294, median 27 gestation weeks). 6 fetuses with unsatisfied 3D-ICRV images quality were excluded. Morphology of sulci and gyri on the brain convex surface could be demonstrated clearly on 3D-ICRV images. Sylvian fissure was the first structure to be recognized. From 25 to 30 weeks, other sulci and gyri became visible. An ascending trend in display rate of sulci was found in this period. Follow up showed no detectable anomalies. Conclusions: 3D-ICRV rendering technology is differentiated from traditional 3D ultrasound. It can provide a vivid and intuitive visualization for sulci and gyri on brain surface prenatally. Moreover, it may offer more new ideas for neurodevelopment exploration.
