{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.
