Dispersal Pattern of Injectate After Cervical Epidural Steroid Injection Evaluated With Magnetic Resonance Imaging.

Study Design: Prospective, nonrandomized, clinical study.

Objective: Epidural steroid injections (ESIs) are an important diagnostic and treatment modality for spine pathology. The success of these injections has been attributed to the anatomic location reached by the injectate.

Dispersal pattern of injectate after lumbar interlaminar epidural spinal injection evaluated with computerized tomography.

Study Design Retrospective analysis of lumbar computed tomographic epidurograms. Objective To evaluate the dispersal pattern of injectate after interlaminar lumbar epidural steroid injections. Summary Prior studies have evaluated the dispersal patterns of injectate after lumbar epidural steroid injections using fluoroscopy with varying results.
