The more we discover about our Universe, the more we realize just how strange and wonderful it is. When Pluto was discovered 80 years ago, we never could have expected the variety of objects in the Solar System. Categorizing Pluto as a dwarf planet helps us better describe our celestial home.
A more detailed neurosonographic evaluation is done in additional coronal and sagittal planes, visualised ideally with transvaginal ultrasound through the anterior fontanelle. Place the vacuum cup on the occiput of the fetal cranium toward the anterior fontanelle. 1] The anterior fontanelle is the unossified area of the skull situated at the junction of the frontal, coronal, and sagittal sutures.
If the anterior height of a vertebral body is 3mm or more less than the posterior height, this is evidence of a wedge-compression fracture. The distance between the posterior aspect of the arch of C1 and the anterior aspect of the odontoid peg should be no more than 3mm in adults and 5mm in children. Assess Harris' ring at the base of C2, overlying the vertebral body. This should remain unbroken anteriorly, posteriorly and superiorly.
