Demonstration of cranial sutures and fontanelles at 15 to 16 weeks of gestation: a comparison between two‐dimensional and three‐dimensional ultrasonography

Abstract

Sutures and fontanelles are usually satisfactorily demonstrated by two-dimensional and three-dimensional ultrasound at 15 to 16 weeks of gestation. The sagittal suture is difficult to visualize using two-dimensional ultrasound, and three-dimensional ultrasound appears to be the best method for its demonstration.

Metopic suture in fetuses with holoprosencephaly at 11 + 0 to 13 + 6 weeks of gestation

“…Three‐dimensional (3D) ultrasound can provide useful information on the normal and abnormal development of the fetal cranial bones and sutures1–3. There is some evidence that growth and ossification of the skull may be influenced by the development of the underlying brain4.…”

Role of 3-D Ultrasound in Clinical Obstetric Practice: Evolution Over 20 Years

“…(i, interpalatal suture; m, maxillary process; ph; pharynx; p, hard palate; pp, ptherygoid process; pns, posterior nasal spine; transverse posterior spine; t, tongue) Assessment of the fetal face and palate using Omniview in a normal fetus at the second-trimester scan. -16 wk of gestation,Ginath et al (2004) maintained that 3-DUS appears to be a better method than 2-DUS for displaying the sagittal suture (50 [100%] vs. 35 [70%], p , 0.001)(Fig. 9).…”

Diagnostic Evaluation of the Fetal Face Using 3-Dimensional Ultrasound

“…14 Conventional 2DUS allows for only limited evaluation of sutures and fontanelles as cross-sectional slices. 14,16 Most cases of craniosynostosis are identified because of an abnormal shape of the head on 2DUS imaging.…”
