gradient light mode, minimum mode, inversion mode, glass body, and color modes. Results: 3D and 4D ultrasound evaluations were performed on 16 fetuses with mean GA 22 weeks (range 14-34). Anomalies included congenital diaphragmatic hernia (two with right sided hernia and one left sided), lung dysplasia (6 cases, of who three had vascular anomalies and three without vascular anomalies), and Thanatophoric dysplasia with small thorax (2 cases), dextrocardia (2 cases), Hydrothorax (1 case), situs inversus totalis (1 case), and situs ambiguous with asplenia (1 case). Conclusion: 3D and 4D techniques are new modalities, which enables higher accuracy, and better views of the fetal thoracic organs and assist the physician in diagnosis the malformations. Performing 3D ultrasound enhances visualization, identification and delineates more clearly the extension of the defect. 3D ultrasound seems to be a promising new tool for precise anatomical description of fetal thoracic organs. P09.08 A rare case of dicephalus twins. The importance of the use of tridimensional ultrasound for the parents
Objective: This study examines the role of virtual reality in the visualization of 3D data volume sets of ambiguous genitalia as acquired by 3D ultrasound. Methods: In 2005 in three patients referred to our department for prenatal ultrasound assessment ambiguous genitalia were diagnosed. Postpartum diagnosis was one case of Russell-Silver syndrome, one case of an XY-female with normal labia majora and an enlarged clitoris and a case with an unusual type of cloacal malformation with an enlarged clitoris, prominent preputium and single urogenital sinus. Prenatally, patients were examined by 2D and 3D ultrasound and subsequently the images obtained at 3D ultrasound were visualized in the Barco I-Space virtual reality system. Results: In these cases, prenatal diagnosis was impossible with 2D ultrasound. 3D ultrasound provided an impression of ambiguity, however this was incorrect in two cases. In the I-Space, a better impression of genital ambiguity was established. Particularly the bi-ocular depth perception provided by the I-space was useful when faced with the task of differentiating a micropenis from an enlarged clitoris. Conclusions:The presence of ambiguous genitalia in a baby post partum presents a major diagnostic dilemma that few clinicians would attempt on a purely visual basis without resorting to palpation and physical examination. Prenatal ultrasound of such a condition can at best only alert to a condition that will need further examinations post partum, thus unfortunately raising parents' anxiety level. A 3D virtual reality technique that improves depth perception can improve visualisation of difficult anatomical structures such as ambiguous genitalia. OP09.17 Prenatal diagnosis of congenital heart disease by spatio temporal image correlation 3D echocardiography (STIC)A.-C. Müller Brochut, P. Hohlfeld, N. Beurret Lepori, C. Maillard, E. J. Meijboom, Y. Vial Centre Hospitalier Universitaire Vaudois, SwitzerlandObjective: The development of new echocardiographic techniques has been a cornerstone in the advent of prenatal diagnosis of congenital heart disease (CHD), the introduction of real-time 3D color Doppler echocardiography (4D) does not form an exemption. We introduced a systemic real time 4D (STIC) approach and correlated the use of this technique with 2D Doppler studies for the prenatal diagnosis of CHD. Results:The 53 STIC studies were obtained in 19 fetus with CHD (major and minor) between 14 and 36 weeks gestation (mean: 27). Cardiac analysis was possible in 18 studies (95%) with a complete diagnosis in 74%, partial in 16%, requiring modification in 5% (1 study) and unobtainable in 5% of the echocardiographies. Complete diagnosis could be obtained in 89% between 21 and 27 weeks, but diminished to 63% between 30 and 36 weeks. In 1 case of complex CHD, which was partially missed before, could be completely diagnosed offline later, which was confirmed postnatally. Conclusions:Good correlation between direct online 2D and indirect offline STIC diagnosis, suggests that this new technique can be re...
