General Information

• It is an expectation that all patients receive care/services from a licensed clinician. All appropriate supporting documentation, including recent pertinent office visit notes, laboratory data, and results of any special testing must be provided. If applicable: All prior relevant imaging results and the reason that alternative imaging cannot be performed must be included in the documentation submitted. 
• Where a specific clinical indication is not directly addressed in this guideline, medical necessity determination will be made based on widely accepted standard of care criteria. These criteria are supported by evidence-based or peer-reviewed sources such as medical literature, societal guidelines and state/national recommendations.
• The guideline criteria in the following sections were developed utilizing evidence-based and peer-reviewed resources from medical publications and societal organization guidelines as well as from widely accepted standard of care, best practice recommendations.

Purpose
Computed tomography (CT) is performed for the evaluation of the cervical spine. CT may be used as the primary imaging modality, or it may complement other modalities. Primary indications for CT include conditions, e.g., traumatic, neoplastic, and infectious. CT is often used to study the cervical spine for conditions such as degenerative disc disease when MRI is contraindicated. CT provides excellent depiction of bone detail and is used in the evaluation of known fractures of the cervical spine and for evaluation of postoperative patients.

Special Note
If there is a combination request* for an overlapping body part, either requested at the same time or sequentially (within the past 3 months), one of the following must be demonstrated:

• The results of the prior study should be inconclusive or show a need for additional or follow-up imaging evaluation 
• The office notes should clearly document an indication why overlapping imaging is needed and how it will change management for the patient.

(*Unless approvable in the combination section as noted in the guidelines).

Rationale
*Conservative Treatment
Non-operative conservative treatment should include a multimodality approach consisting of at least one (1) active and one (1) inactive component targeting the affected region.
Active Modalities

• Physical therapy
• Physician-supervised home exercise program**
• Chiropractic care

Inactive Modalities

• Medications (e.g., NSAIDs, steroids, analgesics)
• Injections (e.g., epidural injection, selective nerve root block)
• Medical Devices (e.g., TENS unit, bracing)

**Home Exercise Program
The following two elements are required to meet conservative therapy guidelines for HEP⁽¹⁾:

• Documentation of an exercise prescription/plan provided by a physician, physical therapist, or chiropractor; AND
• Follow-up documentation regarding completion of HEP after the required 6-week timeframe or inability to complete HEP due to a documented medical reason (e.g., increased pain or inability to physically perform exercises).

Cervical Myelopathy
Symptom severity varies, and a high index of suspicion is essential for making the proper diagnosis in early cases. Symptoms of pain and radiculopathy may not be present. The natural history of myelopathy is characterized by neurological deterioration. The most frequently encountered symptom is gait abnormality (86%) followed by increased muscular reflexes (79.1%), pathological reflexes (65.1%), paresthesia of upper limb (69.8%) and pain (67.4%).⁽¹¹⁾

NEXUS Criteria for C-Spine Imaging⁽⁴⁶⁾
Clears patients from cervical spine fracture clinically, without imaging when none of the following are present

• Focal neurologic deficit present
• Midline spinal tenderness present
• Altered level of consciousness present
• Intoxication present
• Distracting injury present

Canadian C-Spine Rule⁽⁴⁷⁾
Clinically clears cervical spine fracture without imaging in alert, stable trauma patients.
With all of the following: 

• Low risk factor present
  • Sitting position in the ED, ambulatory at any time, delayed (not immediate onset) neck pain, no midline tenderness. Simple rearend motor vehicle collision (MVC) (not 
• simple if pushed into traffic, hit by bus/large truck, rollover, hit by high-speed vehicle) AND
• Able to actively rotate neck 45° left and right AND
• None of the following high-risk factors
  • Age ≥65 years
  • Extremity paresthesia’s 
  • Dangerous mechanism (e.g., fall from ≥3 ft (0.9 m) / 5 stairs, axial load injury, high speed MVC/rollover/ejection, bicycle collision, motorized recreational vehicle)

Gait and Spine Imaging
Table 1^(48–51)

Gait	Characteristic	Work up/Imaging
Hemiparetic	Spastic unilateral, circumduction	Brain and/or, Cervical spine imaging based on associated symptoms
Diplegic	Spastic bilateral, circumduction	Brain, Cervical and Thoracic Spine imaging
Myelopathic	Wide based, stiff, unsteady	Cervical and/or Thoracic spine MRI based on associated symptoms
Cerebellar Ataxic	Broad based, clumsy, staggering, lack of coordination, usually also with limb ataxia	Brain Imaging
Apraxic	Magnetic, shuffling, difficulty initiating	Brain Imaging
Parkinsonian	Stooped, small steps, rigid, turning en bloc, decreased arm swing	Brain Imaging
Choreiform	Irregular, jerky, involuntary movements	Medication review, consider brain imaging as per movement disorder Brain MR guidelines
Sensory ataxic	Cautious, stomping, worsening without visual input (ie + Romberg)	EMG, blood work, consider spinal (cervical or thoracic cord imaging) imaging based on EMG
Neuropathic	Steppage, dragging of toes	EMG initial testing; BUT if there is a foot drop, lumbar spine MRI is appropriate without EMG Pelvis MR if there is evidence of plexopathy
Vestibular	Insecure, veer to one side, worse when eyes closed, vertigo	Consider Brain/IAC MRI

CT Myelogram
Myelography is the instillation of intrathecal contrast media under fluoroscopy. Patients are then imaged with CT to evaluate for spinal canal pathology. Although this technique has diminished greatly due to the advent of MRI due to its non-invasiveness and superior soft-tissue contrast, myelography is still a useful technique for conventional indications, such as spinal stenosis, when MRI is contraindicated or nondiagnostic or surgeon preference (see guidelines above), brachial plexus injury in neonates, radiation therapy treatment planning, and cerebrospinal fluid (CSF) leak.⁽⁵²⁾

Contraindications and Preferred Studies

• Contraindications and reasons why a CT/CTA cannot be performed may include: impaired renal function, significant allergy to IV contrast, pregnancy (depending on trimester)
• Contraindications and reasons why an MRI/MRA cannot be performed may include: impaired renal function, claustrophobia, non-MRI compatible devices (such as non-compatible defibrillator or pacemaker), metallic fragments in a high-risk location, patient exceeds wight limit/dimensions of MRI machine

SUMMARY OF EVIDENCE
Diagnosis and Treatment of Cervical Radiculopathy from Degenerative Disorders⁽¹⁾
Study Design: The document outlines the development of clinical guidelines by the North American Spine Society (NASS) for the diagnosis and treatment of cervical radiculopathy from degenerative disorders. The guidelines were developed through a systematic review of the literature and expert consensus. The methodology included a comprehensive literature search, evidence analysis, and formulation of evidence-based recommendations.

Target Population: The guidelines are intended for adult patients (18 years or older) with a chief complaint of pain in a radicular pattern in one or both upper extremities related to compression and/or irritation of one or more cervical nerve roots. The target population includes patients with varying degrees of sensory, motor, and reflex changes, as well as dysesthesias and paresthesias related to nerve root(s) without evidence of spinal cord dysfunction (myelopathy).

Key Factors:

1. Objective: To provide evidence-based recommendations for the diagnosis and treatment of cervical radiculopathy from degenerative disorders.
2. Scope and Purpose: The guidelines aim to assist practitioners in improving the quality and efficiency of care delivered to patients with cervical radiculopathy from degenerative disorders.
3. Methodology: The guidelines were developed through multidisciplinary collaboration, evidence analysis training, disclosure of potential conflicts of interest, and standardized levels of evidence and grades of recommendation.
4. Recommendations:
   • Diagnosis/Imaging: Suggested diagnostic tests include MRI, CT, and CT myelography. Provocative tests such as the shoulder abduction and Spurling’s tests may be considered.
   • Outcome Measures: Recommended outcome measures include the Neck Disability Index (NDI), SF-36, SF-12, and Visual Analog Scale (VAS).
   • Medical/Interventional Treatment: The role of pharmacological treatment, physical therapy/exercise, manipulation/chiropractics, epidural steroid injections, and ancillary treatments such as bracing, traction, electrical stimulation, acupuncture, and TENS are discussed.
   • Surgical Treatment: Various surgical options are compared, including anterior cervical decompression with fusion (ACDF), anterior cervical decompression alone (ACD), anterior cervical decompression and fusion with instrumentation (ACDFI), and posterior decompression with or without fusion.

ACR Appropriateness Criteria® Cervical Pain or Cervical Radiculopathy (6)

Study Design: The study design involves a systematic review of literature and expert panel recommendations to establish guidelines for imaging procedures in various clinical scenarios related to cervical pain and radiculopathy. The criteria are revised periodically to incorporate new evidence and advancements in imaging technology.

Target Population: The target population includes adults experiencing cervical pain or cervical radiculopathy. The document addresses different clinical scenarios such as acute or increasing cervical pain without radiculopathy, acute or increasing cervical pain with radiculopathy, prior cervical spine surgery, suspected or known infection, diagnosis of malignancy, suspected cervicogenic headache, chronic cervical pain without radiculopathy, and chronic cervical pain with radiculopathy.

Key Factors

Imaging Procedures: The document categorizes imaging procedures based on their appropriateness for different clinical scenarios. Procedures include radiography, MRI, CT, CT myelography, MRA, bone scan, FDG-PET/CT, and others.

Relative Radiation Levels: Each imaging procedure is assessed for its relative radiation level, indicating the potential adverse health effects associated with radiation exposure.

Clinical Scenarios: The criteria provide specific recommendations for initial imaging based on the presence or absence of trauma, "red flag" symptoms, and other clinical 
indicators.

Expert Panel: The guidelines are developed by an expert panel consisting of radiologists, neurologists, orthopedic surgeons, and other specialists from various institutions.

ACR Appropriateness Criteria® Acute Spinal Trauma⁽¹³⁾
Study Design: The document is a revised guideline by the American College of Radiology (ACR) for the appropriateness of imaging procedures in acute spinal trauma. It includes a summary of literature reviews, expert panel recommendations, and evidence-based criteria for various clinical scenarios.

Target Population: The guidelines focus on patients aged 16 years and older who have experienced acute blunt trauma to the cervical, thoracic, or lumbar spine. Specific criteria are provided for different age groups and clinical conditions, including low-risk patients, those with suspected arterial injury, and obtunded patients

Key Factors:

Imaging Procedures: The document outlines the appropriateness of various imaging modalities such as CT, MRI, MRA, and radiography for different clinical scenarios. It emphasizes the use of CT without IV contrast as the initial imaging modality for most cases.

Clinical Criteria: The guidelines incorporate the NEXUS and Canadian C-Spine Rule (CCR) criteria for determining the need for cervical spine imaging. These criteria are based on factors such as age, mechanism of injury, and clinical symptoms.

Radiation Levels: The document includes relative radiation level designations for each imaging procedure, highlighting the importance of minimizing radiation exposure.

Expert Panel: The guidelines were developed by an expert panel on neurological imaging, including specialists from various institutions and organizations

ANALYSIS OF EVIDENCE
Shared Findings:

Diagnosis and Imaging: All three articles emphasize the importance of imaging in diagnosing cervical spine conditions. "Bono et al 2010" discusses the use of MRI and CT for diagnosing cervical radiculopathy.⁽¹⁾ "Eldaya et al 2024" provides detailed appropriateness criteria for various imaging modalities in different scenarios of cervical 
pain and radiculopathy.⁽⁶⁾ "Hassankhani et al 2024" highlights the role of CT and MRI in acute spinal trauma.⁽¹³⁾

Clinical Guidelines: The articles stress the need for evidence-based clinical guidelines. "Bono et al 2010" outlines the North American Spine Society's guidelines for diagnosing and treating cervical radiculopathy.⁽¹⁾ "Eldaya et al 2024" presents the American College of Radiology's appropriateness criteria for imaging cervical pain and radiculopathy.⁽⁶⁾ "Hassankhani et al 2024" discusses the ACR's guidelines for imaging acute spinal trauma.⁽¹³⁾

Role of MRI: MRI is consistently recommended across all articles for its superior ability to visualize soft tissue abnormalities. "Bono et al 2010" mentions MRI's role in 
diagnosing cervical radiculopathy.⁽¹⁾ "Eldaya et al 2024" lists MRI as appropriate for various cervical pain scenarios.⁽⁶⁾ "Hassankhani et al 2024" emphasizes MRI's 
importance in detecting ligamentous, spinal cord, or nerve root injuries.⁽¹³⁾
