OBJECTIVE
To identify the source of metallic artifacts observed on cervical spine MR studies following anterior cervical diskectomy and fusion (ACD&F), preoperative and postoperative MR studies were done on cadavers using standard spin echo T1, T2, and GRASS imaging.
MATERIALS AND METHODS
An ACD&F was performed on each cadaver at various levels using different combinations of drill burrs, curettes, and suction tips.
RESULTS
Results showed that contact between the drill burr and suction tip produced the worst artifacts; however, artifacts still occurred in cases in which the suction tip was not introduced.
CONCLUSION
This observation suggests that metal flakes from the curettes also produced artifacts. Image distortion was greater on GRASS imaging than on the spin echo imaging.
目的
为了确定在颈椎前路椎间盘切除融合术（ACD&F）后颈椎磁共振成像研究中观察到的金属伪影的来源，使用标准自旋回波T1、T2和梯度回波（GRASS）成像对尸体进行术前和术后磁共振研究。
材料与方法
在每个尸体的不同节段使用不同组合的钻磨头、刮匙和吸引头进行ACD&F手术。
结果
结果表明，钻磨头与吸引头接触产生的伪影最严重；然而，在未引入吸引头的情况下仍会出现伪影。
结论
该观察结果表明，刮匙产生的金属碎屑也会产生伪影。GRASS成像上的图像失真比自旋回波成像上的更大。
