Abstract
Computed tomography-guided puncture is a useful technique for various interventional radiology procedures. Puncture from various locations and angles becomes possible using this technique. Moreover, bone and air do not interfere with the computed tomography image. Therefore, computed tomography-guided puncture is feasible even in difficult cases of ultrasonography-guided procedures. However, a computed tomography-guided procedure can cause radiation exposure to patient and operator. Therefore, utmost attention should be given to minimizing radiation exposure. This study aimed to provide a brief review of pre-procedural preparation and the technical tips for the computed tomography-guided puncture and introduce recent topics related to the radioprotection of computed tomography-guided puncture.
