-The cervical sympathetic and parasympathetic nerves are a potential risk of injury during surgery, target for local anesthetic block and origin of neoplasms. However, there are few reports about imaging anatomy of these nerves. -Although it is difficult to detect the nerves totally, recent high-resolution MR neurgraphy sequences can identify their ganglions. Recognizing the ganglions can have you predict the nerve routes. Exceptionally, hypertrophic neuropathy improves anatomical visualization of the nerve routes. -Previous reports with cadavers are partially different from MR imaging anatomy. Postmortem changes and autopsy procedures may affect morphology and locations of the nerves. High-resolution MR neurography can be gold standard to evaluate anatomical features of the nerves.

1. Imaging technique -High-resolution MR sequences, especially 3D-STIR 2. Sympathetic nerve: the cervical sympathetic trunk -Location and morphology of the ganglions: Superior cervical ganglion, middle cervical ganglion, vertebral ganglion and stellate ganglion -White and gray ramus communications 3. Parasympathetic nerve: the vagus nerve -Location and morphology of the ganglion: the nodose ganglion -The vagus nerve on hypertrophic neuropathy 4. Differences between previous reports with cadavers and MR imaging anatomy
