Intracavitary brachytherapy has an important role in treating cervical cancer. MRI is the optimal imaging technique to visualize the intracavitary brachytherapy probes and MRI-guided intracavitary brachytherapy is expected to increase significantly over the next 5 years. The purpose of this article is to review what a radiologist needs to know about imaging brachytherapy probes including the MR technique, correct positioning of the probes, and associated complications.
MRI-guided intracavitary brachytherapy is an increasingly used therapy for the treatment of cervical cancer. This technique provides excellent visualization of intracavitary brachytherapy devices and allows accurate localization of residual tumor. It is important for radiologists to be familiar with the correct probe positioning as well as any potential complications.
腔内近距离放射治疗在宫颈癌的治疗中具有重要作用。磁共振成像（MRI）是可视化腔内近距离放射治疗探针的最佳成像技术，预计在未来 5 年内，MRI 引导下的腔内近距离放射治疗将显著增加。本文的目的是回顾放射科医生需要了解的有关成像近距离放射治疗探针的知识，包括 MR 技术、探针的正确定位以及相关并发症。
MRI 引导下的腔内近距离放射治疗是一种越来越多地用于治疗宫颈癌的方法。该技术为腔内近距离放射治疗设备提供了极好的可视化效果，并允许对残留肿瘤进行精确定位。放射科医生熟悉正确的探针定位以及任何潜在的并发症非常重要。
