Question 7

A
The "nuchal" sign
B
The "shotgun" sign
C
The "equal" sign
D
The "plus" sign
Question 7 Explanation: 
The protocol for an ultrasound evaluation of the nasal bone is shown in the image. The fetal profile needs to be insonated in the midline plane. This is determined by visualizing the following fetal structures: the hypoechoic region of the thalamus, pons, and medulla oblongata, the echogenic line over the nasal bridge representing the skin, and an echogenic line that is located anteriorly and slightly superiorly to the nasal bridge, which represents the skin over the nasal tip. If the nasal bone is present, an echogenic line is also seen within the substance of the nasal bridge. This line is approximately parallel to the line representing the nasal bridge skin. These two lines form a so-called equal sign. The echogenicity of the nasal bone needs to be greater than that of the skin in order for the nasal bone to be identified as present. The reason for this requirement is that even if the nasal bone is not ossified (i.e. sonographically absent), a very faint echodense line may be seen within the nasal bridge.
