Radiologic evaluation of chronic neck pain

For many years, there were no guidelines for evaluating patients with chronic neck pain. However, in the past 15 years, considerable research has led to recommendations regarding whiplash-associated disorders. This article summarizes the American College of Radiology Appropriateness Criteria for chronic neck pain. Imaging plays an important role in evaluating patients with chronic neck pain. Five radiographic views (anteroposterior, lateral, open-mouth, and both oblique views) are recommended for all patients with chronic neck pain with or without a history of trauma. Magnetic resonance imaging should be performed in patients with chronic neurologic signs or symptoms, regardless of radiographic findings. The role of magnetic resonance imaging in evaluating ligamentous and membranous abnormalities in persons with whiplash-associated disorders is controversial. If there is a contraindication to magnetic resonance imaging, computed tomography myelography is recommended. Patients with normal radiographic findings and no neurologic signs or symptoms, or patients with radiographic evidence of spondylosis and no neurologic findings, need no further imaging studies.
