This project will study patients with cervical radiculopathy. We will evaluate the combined diagnostic and prognostic value of magnetic resonance neurography (MRN), electrodiagnostic (EDX) studies, and historical and physical clinical elements. Specifically, this project will explore whether these data individually or in combination correlate with response to procedural and non-procedural treatment.

Inclusion Criteria:

• Patients presenting with symptoms compatible with acute or subacute unilateral (one-sided) cervical radiculopathy and signs of clinical weakness
• 18-60 years old at the time of evaluation
• Symptom onset of 2 to 12 weeks leading up to baseline visit
• Diagnosis of unilateral cervical radiculopathy, with or without spinal cord compression, based on signs and symptoms, physical exam and supported by MRI findings of radiculopathy (as evidenced by foraminal stenosis/narrowing) based on standard-of-care cervical spine MRI
• Patients who have undergone or have planned electrodiagnostic testing at HSS prior to surgery

Exclusion Criteria:

• Prior cervical surgery or instrumentation
• Those who have had a prior episode of cervical radiculopathy
• History of peripheral neuropathy or another acute or chronic neurodegenerative condition
• History of stroke, cerebellar disease, or central nervous system disease
• Contraindications to undergoing a standard MRI examination (e.g., pregnancy)
• Patients presenting with bilateral cervical radiculopathy
