Artifact arising from metallic hardware can present a major obstacle to computed tomographic imaging of bone and soft tissue and can preclude its use for answering a variety of important clinical questions. The advent of multirow detector computed tomography offers new opportunities to address the challenge of imaging in the presence of metallic hardware. This pictorial essay highlights current strategies for reducing metallic hardware artifacts and presents some illustrative clinical cases.
金属植入物产生的伪影会给骨骼和软组织的计算机断层扫描成像带来重大障碍，并可能使其无法用于回答各种重要的临床问题。多排探测器计算机断层扫描的出现为解决金属植入物存在时的成像挑战提供了新机遇。这篇图文并茂的文章重点介绍了减少金属植入物伪影的当前策略，并展示了一些具有说明性的临床病例。
