Reliability of MRI and Ultrasound in Cervical Epidural Needle Depth Estimation

This intervention involves cervical epidural steroid injection (CESI) for patients with chronic neck and radicular pain. Needle depth is measured pre-procedurally using MRI and ultrasound to predict the ideal needle placement. Fluoroscopy is used during the procedure to confirm and compare these measurements, aiming to evaluate the accuracy of imaging techniques and minimize radiation exposure.
