Purpose: To investigate the feasibility of MR-guided stent angioplasty of iliac artery stenoses under passive visualization. Material and Methods: Three patients with short, concentric stenoses of the iliac arteries were enrolled. The vascular interventions were performed on a 1.5 T MR scanner (Magnetom Symphony, Siemens, Erlangen, Germany). Stents, guidewires, and balloon catheters were visualized on the basis of susceptibility artifacts. Contrast-enhanced MR angiography (ceMRA) was used to localized the stenosis prior to stent deployment. Nitinol stents were placed under MR-guidance using a fast 2D gradient echo technique. Balloon dilatiation was performed with an angioplasty catheter inflated with diluted gadolinium-DTPA. Postinterventional results were evaluated by ceMRA, DSA, and Doppler indices. Results: Position of the stent, stent deployment, and balloon dilatation were depicted by MR. All stents were correctly placed within the stenosis. Stent positions as monitored by MRI were identical to those seen on DSA images. All patients were treated successfully by the MR-guided intervention. Conclusion: An MR-guided stent angioplasty of simple iliac artery stenoses is feasible under passive visualization.
