Magnetically Assisted Remote-controlled Endovascular Catheter for Interventional MR Imaging: In Vitro Navigation at 1.5 T versus X-ray Fluoroscopy

摘要

In an abdominal aortic phantom, the magnetically assisted remote-controlled catheter system was faster and more accurate than a similar nonmagnetic catheter under MR imaging guidance and was similar in catheterization efficiency to standard clinical microcatheterization under conventional x-ray guidance.
