Many factors affect radiation exposure during spine interventional procedures. These include tube selection and position (AP, lateral, or biplane), procedure time, technique, and the requirement for close proximity to patient during the procedure. This educational exhibit discusses several helpful techniques and devices that are available to reduce radiation exposure for the interventionalist and other personnel. Our measurements have shown that additional shielding placed on the patient and/or between the patient and personnel can significantly reduce scatter radiation by up to 98%. The additional shielding includes a 0.5mm lead equivalent apron placed on the patient’s lower torso and legs, 0.5 mm lead equivalent mobile barrier, and a 1.0 mm lead equivalent mobile barrier. We have also demonstrated that using a personal radiation monitor will raise the operator’s awareness to radiation exposure. The audio signal from this device alerts the operator to increases in radiation exposure. Finally, our data demonstrated that by extending the injection tubing length for manual hand injection, the radiation exposure to the operator is significantly reduced.
