The accuracy of steroid injection into the caudal space using ultrasound guidance was comparable with that obtained using fluoroscopic guidance. The authors conclude that ultrasound is preferable ...

A study comparing ultrasound-guided SNRB with fluoroscopy-guided transforaminal epidural steroid injections found that both methods provided similar pain relief and functional improvements for ...

Ultrasound scanning can also be performed immediately after injections to visualise the location of the steroid deposit which appears as echogenic foci or lines, with or without acoustic shadowing.
