Abstract：
The fact that self-locating catheters have a piece of metal at the tip leads to doubt and uncertainty around performing magnetic resonance imaging (MRI) in patients with this type of catheter. We simulated a peritoneum with a weighted catheter to ascertain how the catheter behaved during MRI scans in 1.5 T and 3 T machines. We also reviewed cases in which MRI had been performed in patients with this type of catheter. In the simulation, the tip of the self-locating peritoneal catheter caused a magnetic susceptibility artefact that made it difficult to see nearby areas, but it proved to be a safe device for MRI. 14 MRI scans were performed in patients with self-locating catheters, none in the abdominal area. There were no complications in the patients or the technique after performing MRI.
摘要：
自定位导管在尖端具有一块金属的事实导致对使用这种类型的导管的患者执行磁共振成像(MRI)的怀疑和不确定性。我们用加权导管模拟腹膜，以确定导管在1.5T和3T机器的MRI扫描过程中的行为。我们还回顾了使用这种类型导管的患者进行MRI检查的病例。在模拟中,自定位腹膜导管的尖端引起磁化率伪影，使其难以看到附近区域，但它被证明是MRI的安全装置.对使用自定位导管的患者进行了14次MRI扫描，腹部没有。进行MRI检查后，患者或技术均无并发症。
