Field Inhomogeneity-Based Catheter Visualization. Compared to conventional catheterization under fluoroscopy, MR-guided catheterization has several advantages and disadvantages. The two primary advantages of MR guidance are the lack of X-ray exposure for the patient and medical staff and the good soft tissue contrast, which allows excellent depic

Active Visualization — MR Profilinge easy to identify in the MR image and should be visible throughout the procedure under various imaging conditions. An ideal method would provide some form of high contrast signature for the device, along with high resolution for accurate placement. An additional requirement is speed, to provide the

Safety Issues in the MR Environmentsearch data it can be inferred that more than 100 000 000 diagnostic MR studies have been performed worldwide between the introduction of clinical MRI in the early 1980s and the end of 1996. The number of reported serious complications resulting from these studies is relatively small. A brief litera

Patient Monitoring in the MR Environment. 1995; . and . 1993). Patient monitoring during an MR examination is complicated since the MR system is an extremely hostile environment for other electronic devices and sensors, and at the same time a very sensitive receiver, making the images prone to artifacts. Before devices were commercially a
