A report in the February edition of the Journal of Spinal Disorders and Techniques evaluates radiation exposure during fluoroscopy-guided transforaminal and caudal approaches of lumbosacral epidural steroid injections.
The study included 228 patients who received lumbosacral ESI; 181 patients received transforaminal ESI and 47 received caudal ESI. Fluoroscopy time was 11 to 161 seconds for transforaminal ESI and four to 78 second for caudal ESI.
The researchers found that kerma-area product and fluoroscopy time were positively correlated for both transforaminal and caudal ESI, and after correction for fluoroscopy time KAP was less in transforaminal ESI than caudal ESI.
