Cervical brachalgia: Assessment by cervical CT epidurography post transforaminal injection
Biomedical Imaging and Intervention Journal
|May 26, 2011
Summary
Adjunct cervical CT epidurography (CCTE) offers a viable imaging alternative for cervical impingement when MRI is contraindicated. This method provides clear visualization of the cervical spinal canal and its contents.
Area of Science:
- Radiology
- Neurosurgery
- Pain Management
Background:
- Cervical brachalgia can be caused by spinal canal impingement.
- Fluoroscopic-guided cervical transforaminal injection (TFI) is a common treatment.
- Magnetic resonance imaging (MRI) may be contraindicated for some patients.
Purpose of the Study:
- To evaluate the utility of adjunct cervical CT epidurography (CCTE) for imaging cervical impingement.
- To assess CCTE as an alternative to MRI in patients undergoing TFI.
Main Methods:
- Retrospective review of CCTE images from 9 patients who underwent TFI.
- CCTE performed post-TFI between 1998 and 2003.
- Analysis of image quality for the cervical spinal canal and contents.
Main Results:
- CCTE provided good quality images of the cervical spinal canal.
- Demonstrated the ability to visualize structures relevant to impingement.
- Successful application in patients with contraindications for MRI.
Conclusions:
- Adjunct cervical CT epidurography (CCTE) is a potentially valuable imaging tool.
- It serves as an alternative for evaluating cervical impingement when MRI is not feasible.
- Useful in patients undergoing TFI for cervical brachalgia.
