金属植入物在体模状况下的MRI研究

Phantom study of MRI of metallic implant

目的:探讨有金属(纯钛或钛合金)植入物的病人施行磁共振检查的可行性,寻求伪影最小的最佳成像序列,使得该部分病人能够进行常规的磁共振检查,用以诊断病情、评价手术效果。结论:凡是植入物属于抗磁性金属(如:纯钛、钛合金)的病人,能施行常规的磁共振检查。正确的成像参数、成像序列、成像方法的选择,可以得到好的、能够清楚诊断的MR图像。

Objective: This paper describes and discusses the feasibility of MRI to the patients with implants(Titanium or alloy of Titanium) and seeks imaging sequences of minimal artifacts in order that routine MR examination can be performed which as-sistes diagnosis and postoperative evaluation. Conclusion; MR examination can perform to the patient with metallic implant of diamagnetic substance, for example titanium and alloy of titanium.We can get the optimum MR images if we use accurate parameters, sequences and methods for imaging.
