RT Journal Article SR Electronic T1 Safety of 1000 CT-Guided Steroid Injections with Air Used to Localize the Epidural Space JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP E175 OP E177 DO 10.3174/ajnr.A2316 VO 32 IS 9 A1 Chang, A. A1 Pochert, S. A1 Romano, C. A1 Brook, A. A1 Miller, T. YR 2011 UL http://www.ajnr.org/content/32/9/E175.abstract AB SUMMARY: Historically, ESIs were performed without any imaging guidance, resulting in erroneous placement in up to 30% of injections. Fluoroscopic imaging is now used to guide most procedures. Recently, several reports have described the use of CT to guide ESIs instead of fluoroscopy. CT provides the ability to use air as contrast to localize the epidural space. This retrospective review will discuss findings in 1000 CT-guided ESIs with air localization.
