Diagnostic imaging of the recurrent laryngeal (RLN)
and vagus nerves (VN) could help in surgical planning and in minimizing the
risk of damage to the nerves. However, imaging these nerves is technically
challenging due to their size, location, and physiological motions such as
breathing and swallowing. The
RLN and VN can be visualized on the CISS and T2 TSE, however with a novel phase
navigator, the nerves are better delineated on the motion-compensated T2 TSE compared to the CISS which is un-navigated.
