Case 1
This is an ultrasound image from a normal neck study.
Question 1:
What is the imaging plane?
×
Answer:
This is a transverse plane, analagous to a transverse body section or an axial CT or MR image. The patient's right is on the left, as for all radiologic images. Try to identify the labeled structures before clicking on the labels.

Case 1
This is a normal sweep through the right lobe of the thyroid gland in the transverse plane.
Question 2:
What important anatomic structure (not often well seen on ultrasound) travels near the carotid and jugular, within the same fascial sheath?
×
Answer:
The vagus nerve is within the same fascial sheath as the carotid and jugular, but is often hard to identify on ultrasound as its echogenicity is similar to the surrounding fascia.

Case 1
This is another transverse sweep of the right lobe of the thyroid.
Question 3:
What do you notice about the jugular during the course of this sweep?
×
Answer:
The jugular is getting larger and smaller. This is likely due to variations in venous pressure due to respiration.
