A novel ultrasound guided approach for lumbar periradicular injections with investigating the radicular artery nearby (IRAN) technique

Abstract

Ultrasound as a portable and accessible device has attracted the attention of pain specialists and is now used for spine injections. As spine injection is more difficult compared to other pain injection techniques, it did not find a routine place in practice. But the transforaminal injection(TF) is still challenging and pain interventionists are always searching for new techniques to decrease the chances of intravascular injection .Intravascular injection has always been a barrier when it comes to choosing ultrasound as a sole modality for spine injection.
