1.Start simple:
For neck visualization, plain X-ray and US are a good place to start. Plain images will provide information about general structure, presence of osteophytes and the integrity of the intravertebral spaces. US will give information of soft tissues, and is the image of choice for salivary glands, thyroid gland, parathyroid, lymph nodes and cysts.
2.Step up:
Advanced techniques include CT (usually with contrast) for cervical adenopathy, tumors, and any other condition where anatomic delineation is needed.
A MRI will help to assess presence and extension of neurogenic tumors, vascular malformations, neck masses and angiofibromas.
