一侧行人工股骨头置换术后,在需要对对侧髋关节进行CT检查时,用常规双侧对称的方法扫描会产生严重的金属伪影,影响诊断。作者探索一种可以避开置换侧股骨头的扫描方法,介绍如下。操作步骤及要点:(1)病人体位为待检侧侧卧位。该侧贴近检查床较易固定,且位于扫描野中心区,同时也 Side of the artificial femoral head replacement, the need for contralateral hip CT examination, the use of conventional bilateral symmetry of the scan will produce serious metal artifacts, the impact of diagnosis. The authors explore a scanning method that can avoid the replacement side of the femoral head, described below. Operation steps and points: (1) the patient position to be tested lateral position. The side closer to the examination bed easier to fix, and is located in the center of the scan field, but also
