Introduction of ultrasound has revolutionized the antenatal diagnosis of multiple pregnancies. Indeed, two-dimensional sonography (2D) is still the primary modality for the diagnosis and evaluation of multiple pregnancies. However, 2D sonography may be replaced by three-(3D) and four-dimensional (4D) sonography whenever appropriate. New technique s...

Context 1
... gestational sacs have to be recognized in the case of trichorionic triamniotic triplets ( Figure 3). However, even when two gestational sacs are seen, the diagnosis of triplets is not yet excluded, and the possibility of dichorionic triamniotic triplets (complex chorionicity) should be taken in consideration (Figure 4). Counting of the number of embryos is essential for diagnosis of triplets. ...

... »Y« zone assessment should be combined with other parameters for determination of chorionicity. 11 In the case of dichorionic-triamniotic triplets (complex placentation), the placenta is represented by the T-sign and lambda sign with one thin and one thick membrane ( Figure 4). Using conventional sonography it is difficult to distinguish single and fused placentas of the twins, which is even more difficult in triplet pregnancy. ...
