New FactFinder on Digital Subtraction Imaging for Transforaminal Injections

FACT: The published evidence demonstrates superior sensitivity of digital subtraction imaging (DSI) compared with live fluoroscopy alone in detecting inadvertent vascular injection. The degree of sensitivity of DSI for the detection of vascular flow is operator dependent. Importantly, use of this technology does not intrinsically guarantee detection of inadvertent intravascular injection.
