PURPOSE
To develop and test a novel interactive real-time MRI environment that facilitates image-guided cardiovascular interventions.
MATERIALS AND METHODS
Color highlighting of device-mounted receiver coils, accelerated imaging of multiple slices, adaptive projection modes, live three-dimensional (3D) renderings and other interactive features were utilized to enhance navigation of devices and targeting of tissue.
RESULTS
Images are shown from several catheter-based interventional procedures performed in swine that benefit from this custom interventional MRI interface. These include endograft repair of aortic aneurysm, balloon septostomy of the cardiac interatrial septum, angioplasty and stenting, and endomyocardial cell injection, all using active catheters containing MRI receiver coils.
CONCLUSION
Interactive features not available on standard clinical scanners enhance real-time MRI for guiding cardiovascular interventional procedures.
目的
开发并测试一种新型交互式实时磁共振成像（MRI）环境，以促进图像引导的心血管介入治疗。
材料与方法
利用设备安装的接收线圈的颜色高亮显示、多层快速成像、自适应投影模式、实时三维（3D）渲染及其他交互式功能，增强设备导航和组织靶向。
结果
展示了在猪身上进行的几种基于导管的介入手术的图像，这些手术受益于这种定制的介入MRI界面。其中包括主动脉瘤的腔内修复、心脏房间隔球囊造口术、血管成形术和支架置入术以及心内膜细胞注射，所有这些手术均使用含有MRI接收线圈的有源导管。
结论
标准临床扫描仪所没有的交互式功能增强了实时MRI对心血管介入手术的引导能力。
