The Reliability of a Grading System for Digital Subtraction Imaging Quality During Cervical Transforaminal Epidural Steroid Injection.
Abstract
Digital subtraction imaging (DSI) decreases the risk of intravascular injection during cervical transforaminal epidural steroid injection (CTFESI); however, sequence acquisition and interpretation are operator-dependent skills. This study tests the reliability of a grading system to determine adequate DSI during CTFESI.
