We describe an interactive, intraoperative imaging-guided method for performing endoscopic sinus surgery (ESS) within a vertically open MR system. The procedure was performed with intraoperative imaging using a 0.5-T magnet with a 56-cm vertical gap. Interactive control of imaging planes was accomplished by optical tracking with two infrared light-emitting diodes mounted on an aspirator probe. The probe's position defined the location of the orthogonal imaging planes. Twelve patients with varying degrees of sinus disease underwent ESS with MR imaging guidance. Patients had acute and chronic sinusitis, nasal polyposis causing airway obstruction, or tumor requiring tissue biopsy. All procedures were performed with the patients under general anesthesia. The integration of endoscopy with optical tracking and intraoperative interactive imaging allowed localization of anatomic landmarks during ESS. No complications were encountered.
我们描述了一种在垂直开放式磁共振（MR）系统内进行内窥镜鼻窦手术（ESS）的交互式术中成像引导方法。该手术使用具有56厘米垂直间隙的0.5-T磁体进行术中成像。成像平面的交互式控制通过安装在吸引器探头上的两个红外发光二极管进行光学跟踪来完成。探头的位置定义了正交成像平面的位置。12例不同程度鼻窦疾病的患者在MR成像引导下接受了ESS。患者患有急性和慢性鼻窦炎、导致气道阻塞的鼻息肉病或需要组织活检的肿瘤。所有手术均在患者全身麻醉下进行。内窥镜与光学跟踪和术中交互式成像的整合使得在ESS期间能够定位解剖标志。未发生并发症。
