Strategy to reduce radiation exposure in postoperative spinal computed tomography scans

BACKGROUND: When diagnosing and treating spinal disorders, spine surgeons commonly utilize computed tomography (CT) scans preoperatively, intraoperatively, and postoperatively. METHODS: This article reviews the literature regarding the potentially harmful effects of X-rays, specifically from CT scans. RESULTS: The risk for damaging DNA and developing cancer increases with increasing scan length (e.g., increasing amount of radiation received). CONCLUSION: When assessing postoperative status, CT scans should be directed only through the area of specific interest to limit the total dose of radiation received by the patient.
