“…The above drawbacks have recently forced scientists to start looking for alternative imaging methods to perform cardiac catheterizations [3], [4]. One of the new methods that can provide distinct advantages over X-ray fluoroscopy is magnetic resonance imaging (MRI).…”

“…This increases the necessity to reduce the radiation exposure due to diagnosis and interventions to a minimum. However, after initial studies first on animal models and later on patients that were able to show feasibility and advantages [1,61,62], the use of endovascular MRI for this indication has barely been pursued in recent years due to a lack of availability of instruments and the effort and cost of adapting currently available units to endovascular interventions. To still be able to profit from the advantages of MRI, MRI datasets are increasingly being superimposed on angiography images used for interventions [63,64].…”

ABSTR AC TBackground MRI is attractive for the guiding and monitoring of interventional procedures due to its high intrinsic soft tissue contrast and the possibility to measure physiologic parameters like flow and cardiac function.Method The current status of interventional MRI for the clinical routine was analyzed.Results The effort needed for the development of MR-safe monitoring systems and instruments initially resulted in the application of interventional MRI only for procedures that could not be performed by other means. Accordingly, biopsy of lesions in the breast, which are not detectable by other modalities, has been performed under MRI guidance for decades. Currently, biopsies of the prostate under MRI guidance are established in a similar fashion. At many sites blind biopsy has already been replaced by MR-guided biopsy or at least by the fusion of MR images with ultrasound. Cardiovascular This document was downloaded for personal use only. Unauthorized distribution is strictly prohibited.interventions are performed at several centers for ablation as a treatment for atrial fibrillation. Conclusion IntroductionMRI has an intrinsically high soft-tissue contrast and can be used to measure physiological parameters, such as blood flow (flow rate and flow volume), diffusion, temperature, and movement. Since its introduction into the clinical routine in the 1980 s, it has also been used for guiding and monitoring interventions. However, in contrast to CT and ultrasound, the use of MRI for guiding interventions requires significant technical effort. Due to the disruptive effect of the strong main magnetic field and the alternating electromagnetic fields, the monitoring of patients during an intervention by measuring ECG signals, oxygen saturation, or blood pressure requires special equipment. These monitoring systems must not interfere with the MRI scan and must be MR-safe (according to DIN EN 62 570:2010 -05). The list of requirements regarding monitoring equipment provides an indication of the development effort, with suitable monitoring equipment representing only one of the components necessary for MR-guided interventions.In addition to MRI safety, all catheters and instruments must be adapted to this modality. To ensure MRI safety, metal must be largely avoided since, depending on the length and orientation to the main magnetic field, it can heat up and consequently even result in burns. Achieving rigidity and torsion stability of catheters or guide wires without the use of metal for reinforcement represents a technical challenge. In the case of needles, breaking resistance is one of the more difficult properties to achieve for MR-safe designs. Moreover, instruments must be able to be effectively visualized without adjacent structures being superimposed by artifacts. The tip must be able to be identified and definitively differentiated from the shaft since MRI as a cross-sectional imaging method typically uses individual slices even for guiding interventions and does not use projections as in fluoroscopy...

“…Due to the lack of clinically approved instruments, only a few reports can be found in the literature about applications in patients (4,64,79,80). In these clinical pilot studies the conventional procedure was largely copied from fluoroscopy or DSA, and the general feasibility of MR-guided endovascular interventions could be shown.…”

“…Additionally, MRI provides morphologic as well as functional information such as blood flow, tissue oxygenation, diffusion, perfusion, and temperature changes-this broad variety of techniques is currently not available with any other imaging modality alone (1). Due the continued development of MR hardware for faster image acquisition and reconstruction, along with developments such as steady state and parallel imaging techniques, real-time MR imaging is now a clinical reality (2)(3)(4). With the trend toward shorter and more open magnet designs, endovascular MR-guided interventions have evolved from a research tool to a preclinical method over the last decade with a few applications that have entered the clinical arena.…”

Magnetic resonance imaging (MRI) offers several advantages over other imaging modalities that make it an attractive imaging tool for diagnostic and therapeutic procedures. This tremendous potential of MRI has provided the rationale for increased attention toward MR-guided endovascular interventions. MR guidance has been used recently to navigate endovascular catheters and deliver stents, vena cava filters, embolization materials, and septum closure devices. However, its potential goes beyond just copying existing procedures toward the development of new minimally invasive techniques that cannot be performed with conventional guiding techniques. Because of technical limitations and safety issues associated with some of the currently available devices, a limited number of clinical studies have been performed so far. The overall success for this developing field requires considerable interdisciplinary research within both the interventional and the MR community. Only through a combined effort can this complex technology find its way into clinical practice. This review discusses the hardware and software improvements that have helped to advance endovascular interventions under MR imaging guidance from a pure research tool to become a clinical reality. In addition, technical and safety issues specific to endovascular MR image guidance will be described and practical applications will be shown that take advantage of the benefits of MR for endovascular interventions.
