Purpose

Purpose: To quantify the radiation exposure doses to the operator during interventional spine procedures performed with CT-guidance, and relate these to the radiation used to perform the CT examination (Dose Length Product).

Methods & Materials

Method: A variety of 10 consecutive percutaneous interventional spine procedures were performed under CT-guidance on a GE Lightspeed 16 CT scanner. The CT-guided procedures were performed using intermittent repeated low dose image acquisitions (3 slices per acquisition) to view needle advancement. The radiologist performing these procedures remained in the CT room, standing at a distance of about one meter from the CT gantry, during the imagesâ
