Ultrasound may enhance lumbar level identification accuracy; leaves open whether it improves procedural outcomes in randomized settings.
Does ultrasound imaging improve the accuracy of identifying lumbar intervertebral levels compared to palpation in patients undergoing lumbar X-ray?
Ultrasound imaging is significantly more accurate than palpation for identifying lumbar intervertebral levels, reducing the risk of being more than one level off.
Furness et al. (2002) studied this question.
