Summary

The aim of this clinical trial is to investigate the effects of local anesthetic diffusion range and sensory block range during retro-SCTLB(retro superior costotransverse ligament space block) and TPVB(thoracic paravertebral block) in patients undergoing CT-guided lung nodule localization. The main issue of the study is to determine the differences in the diffusion range and sensory block range of local anesthetics between the retro-SCTLB and TPVB nerve block methods.
