开放磁共振成像(MRI)的最新发展为下一阶段图像引导的外科和介入手术提供了机会。本研究的目的是评价开放式MRI手术室系统在气腹下进行腹腔镜手术的可行性。方法5例患者在自行研制的卧式0.4-T开放式MRI手术室的实时增强现实导航系统下进行了腹腔镜手术。在手术中，腹腔镜监护仪清楚地显示了腹膜内结构的增强现实模型，如胆总管和膀胱，以及假体的正确位置。导航帧速率为8帧/min。导航病例平均基准配准误差为6.88±6.18 mm。我们能够使用磁共振不兼容的手术器械走出5-Gs限制区域，以及传统的腹腔镜手术，并使用开放式MRI开发了实时增强现实导航系统。结论在开放式MRI手术区，使用我们的实时增强现实导航系统进行腹腔镜手术是一个可行的选择。
BackgroundThe recent development of open magnetic resonance imaging (MRI) has provided an opportunity for the next stage of image-guided surgical and interventional procedures. The purpose of this study was to evaluate the feasibility of laparoscopic surgery under the pneumoperitoneum with the system of an open MRI operating theater.MethodsFive patients underwent laparoscopic surgery with a real-time augmented reality navigation system that we previously developed in a horizontal-type 0.4-T open MRI operating theater.ResultsAll procedures were performed in an open MRI operating theater. During the operations, the laparoscopic monitor clearly showed the augmented reality models of the intraperitoneal structures, such as the common bile ducts and the urinary bladder, as well as the proper positions of the prosthesis. The navigation frame rate was 8 frames per min. The mean fiducial registration error was 6.88 ± 6.18 mm in navigated cases. We were able to use magnetic resonance–incompatible surgical instruments out of the 5-Gs restriction area, as well as conventional laparoscopic surgery, and we developed a real-time augmented reality navigation system using open MRI.ConclusionsLaparoscopic surgery with our real-time augmented reality navigation system in the open MRI operating theater is a feasible option.
