This chapter discusses the accuracy and safety of lumbar transforaminal or nerve root (periradicular) injections under CT guidance. To maximize procedure accuracy and minimize complications, spinal injections are best performed with image guidance. Though fluoroscopic guidance has been used for decades, greater accuracy and possibly greater safety can be achieved with CT guidance. The radiation exposure is operator dependent, and maintaining the lowest possible dose is critical in optimizing patient care. This is also true for fluoroscopic guidance, for which coning and intermittent exposure are used as well. The future may usher in ultrasound and magnetic resonance imaging guidance without the associated radiation exposure. For interventional practitioners, ensuring patient safety and efficacy goals remains a priority, and needs to evolve with advances in technology.
