A Clinical Guide for Chiropractors, Physical Therapists, and Primary Care Physicians
Magnetic resonance imaging (MRI) is the gold standard for evaluating cervical spine pathology involving neural structures, including the spinal cord, nerve roots, and surrounding soft tissues. MRI findings frequently guide referral decisions, particularly when neurological compromise or structural instability is present.
However, degenerative findings are extremely common, especially in asymptomatic adults over age 40. Studies demonstrate that over 60% of asymptomatic individuals have disc bulges, and over 20% have spinal cord compression without symptoms. Therefore, the clinical challenge is distinguishing incidental findings from those that represent clinically significant pathology requiring specialist evaluation.
This article reviews MRI findings that warrant referral to a spine specialist or neurosurgeon, with emphasis on spinal cord compression, signal change, severe stenosis, progressive neurological risk, and structural instability.
Many MRI abnormalities do not require referral if the patient is neurologically intact and symptoms are stable. Common incidental or low-risk findings include:
Referral decisions should focus primarily on findings associated with:
MRI findings must always be interpreted in conjunction with clinical presentation.

Spinal cord compression occurs when surrounding structures reduce the available space for the spinal cord, producing deformation. MRI may show:
Compression may result from:
Spinal cord compression significantly increases risk of cervical myelopathy, which may cause:
Even in the absence of symptoms, moderate to severe cord compression warrants specialist evaluation due to risk of progression.
T2-weighted MRI may show hyperintense signal within the spinal cord. This represents:
T1 hypointensity represents more advanced injury and correlates with worse prognosis.
Cord signal change is strongly associated with:
Multiple studies show that T2 signal change correlates with poorer functional outcomes. Referral is recommended when cord signal abnormality is present, even if symptoms are mild.
Central canal stenosis refers to narrowing of the spinal canal. MRI indicators include:
Severity categories:
Severe cervical stenosis significantly increases risk of:
Patients with severe stenosis should be referred even in the absence of severe symptoms.
Disc herniations may compress:
Important characteristics include:
Referral is appropriate when herniation causes:
Large central disc herniations carry risk of acute neurological deterioration.
Foraminal stenosis compresses exiting nerve roots. MRI findings include:
Referral is indicated when MRI findings correlate with:
Severe foraminal stenosis with weakness warrants specialist evaluation.
OPLL appears as a thickened, ossified ligament along the posterior vertebral bodies. It often produces:
OPLL is associated with:
Referral is recommended when OPLL causes significant stenosis or cord compression.
While MRI is not the primary modality for diagnosing instability, it may show indirect indicators such as:
Instability increases risk of:
Referral is appropriate when instability is suspected.
MRI findings combined with clinical signs such as:
represent a clear indication for referral. Early surgical evaluation is associated with better neurological outcomes.
MRI may detect spinal cord lesions such as:
These require specialist evaluation and often urgent referral.
MRI findings such as:
require urgent referral. These may cause rapid neurological deterioration.
Cervical kyphosis may contribute to spinal cord compression. MRI may show:
Referral is appropriate when deformity contributes to neural compromise.
Patients with congenitally narrow canals are at increased risk of myelopathy. MRI findings include:
These patients may deteriorate earlier and should be evaluated by a specialist.
Findings that may be managed conservatively include:
Referral may still be appropriate if symptoms persist or worsen.
MRI findings must be interpreted in conjunction with:
MRI abnormalities alone do not always require intervention. However, certain findings — particularly spinal cord compression — warrant specialist evaluation regardless of symptom severity.
Chiropractors, physical therapists, and primary care physicians frequently obtain or review MRI findings. Early identification of high-risk MRI findings allows:
Cervical manipulation is generally contraindicated in patients with significant cord compression.
View Dr. Wascher’s documented career outcomes — complete transparency for referring providers and patients alike.
Numerous studies demonstrate that outcomes are superior when:
Delayed referral may result in permanent neurological impairment.

MRI is the gold standard for evaluating cervical spine pathology and identifying patients who require referral to a spine specialist.
MRI findings that require referral include:
Spinal cord compression is the most important finding requiring referral, even in patients with mild or subtle symptoms.
Cord signal change indicates spinal cord injury and is associated with worse outcomes if untreated.
Common degenerative findings such as mild disc bulges or mild stenosis may be managed conservatively unless neurological deficits or progression occur.
Early referral improves neurological outcomes and helps prevent permanent spinal cord injury. Chiropractors, physical therapists, and primary care physicians play a critical role in identifying concerning MRI findings and facilitating timely specialist evaluation.
