ABSTRACT
Transpedicular screw and rod internal fixation system is the common implants in spinal surgery. Multi-slice spiral CT and magnetic resonance imaging can generate section image, become routine imaging modality in the assessment of the postoperative spinal patients. Magnetic resonance imaging can evaluate the bone marrow and soft tissue, which is the first choice for examination. However, to the patients with metal implants, the existed metal artifacts can decrease the imaging quality. Therefore, multi-slice spiral CT is an important evaluation method for inserted material, os integumentale and anatomy. This article reviewed the production mechanism of metal-related artifacts, influencing factors and decreasing technique.
