Magnetic resonance imaging (MRI) is now essential in stereotactic radiotherapy (SRT) planning for brain tumors because of its excellence in soft-tissue contrast and high spatial resolution. However, MRI distortion is sometimes difficult to recognize, and it may cause large misalignments in radiotherapy planning. In this case report, we will show how much difference in the dose distribution of SRT can be made by using MRI without distortion correction.
由于磁共振成像（MRI）在软组织对比度和高空间分辨率方面表现出色，它目前在脑肿瘤的立体定向放射治疗（SRT）计划中至关重要。然而，MRI畸变有时难以识别，并且它可能在放射治疗计划中导致较大的对准误差。在本病例报告中，我们将展示在不进行畸变校正的情况下使用MRI时，SRT的剂量分布会有多大差异。
