Journal Name

1) Bibliography
Waly, F. J., Abduljabbar, F. H., Fortin, M., Nooh, A., & Weber, M. (2017). Preoperative Computed Tomography Myelography Parameters as Predictors of Outcome in Patients With Degenerative Cervical Myelopathy: Results of a Systematic Review. Global Spine Journal, 7(6), 521-528. doi:10.1177/2192568217701101

2) Purpose of the Article
The purpose of this article was to determine the preoperative computed tomography (CT) myelogram imaging parameters in patients diagnosed with degenerative cervical myelopathy (DCM) that correlate with severity of DCM and predict postoperative patients’ functional outcome. 

3) Brief Description of Procedure and Findings/Results
This article summarizes that even though MRI has become an indispensable modality for diagnosing cervical myelopathy, CT myelography remains a valuable alternative diagnostic modality in cases where MRI is contraindicated. Moreover, CT myelography is superior to MRI for assessing foraminal stenosis and distinguishing bony lesions from soft tissue lesions. To date, most studies have focused on different MRI characteristics as possible predictors of surgical outcomes in patients with DCM. The evidence with regard to the clinical value of CT myelogram imaging parameters in patients with cervical myelopathy is conflicting. It remains uncertain whether changes on CT myelogram imaging represent worsening of the disease process and should be considered as a surgical indication, even in less clinically advanced cases of myelopathy.

4) Conclusions and Comments
The article concludes that the CT myelography plays a complementary role for diagnosing DCM in patients who cannot undergo MRI, and it may help assist surgeons in deciding the most appropriate treatment strategy.

5) The opinion of the Article
I thought this article was somewhat easy to understand. It gave me a better understanding of important endpoint of future clinical research to clarify the predictive features associated with both CT and MRI in patients with DCM and for whom surgery is recommended.
