Diagnostic Evaluation and Treatment for Cervical Canal and Foraminal Narrowing

Diagnostic Evaluation

MRI of the cervical spine without contrast is the recommended initial imaging modality for patients with suspected cervical radiculopathy, correctly identifying approximately 88% of lesions, according to the American College of Radiology 1
CT scanning should be considered as an alternative when MRI is contraindicated, particularly for evaluating bony structures, though it is less sensitive for nerve root compression, as noted by the American College of Radiology 1
Caution should be exercised when interpreting imaging findings, as MRI frequently shows false-positive and false-negative results, and abnormalities are often present in asymptomatic patients, as reported by the American College of Radiology and the Journal of the American College of Radiology 1, 2
SPECT/CT imaging may be useful in identifying pain generators in patients with chronic cervical spine pain, with studies showing identification of potential pain sources in 92% of patients, according to the Journal of the American College of Radiology 3, 4

Surgical intervention should be considered when conservative treatment fails to provide adequate relief, as recommended by the American College of Neurosurgery 1
Intolerable symptoms that persist despite adequate non-operative management may require surgical intervention, as suggested by the Journal of Neurosurgery 5
Posterior laminoforaminotomy is recommended for symptomatic cervical radiculopathy resulting from soft lateral cervical disc displacement or cervical spondylosis with resultant narrowing of the lateral recess, with good to excellent outcomes in 93-95% of patients, according to the Journal of Neurosurgery and the American College of Neurosurgery 5, 6, 1

Abnormal levels on MRI do not always correspond to clinical examination findings, making correlation between imaging and symptoms essential, as emphasized by the American College of Radiology and the Journal of the American College of Radiology 2, 1
Early recognition and treatment before the onset of spinal cord damage is essential for optimal outcomes in cases progressing to myelopathy, although this fact is not directly cited, a similar concept is mentioned in relation to surgical consultation if symptoms persist beyond 3 months, as recommended by the Journal of Neurosurgery 5
