Letter to the editor: the importance of accurate imaging data in ultrasound-guided techniques used in cadaveric studies

We read with great interest the article by Kim et al,1 a cadaveric study comparing paravertebral (PV) and intertransverse process blocks at the level of the T2–T3 intervertebral space, evaluating the spread of 10 mL of latex dye to neural structures. While the study’s originality is insightful, several issues warrant discussion.
