Ultrasound of normal neck vessels

Transverse ultrasound images of the right neck demonstrate normal anatomy, including the internal jugular vein (blue arrow), common carotid artery (red arrow), sternocleidomastoid muscle (SCM), and thyroid gland (T). B shows collapse of the internal jugular vein when compression is applied with the transducer. The carotid artery is not easily compressed with light probe pressure.
