Implementation of Magnetic Resonance Safety Program for Radiation Oncology.
Pract Radiat Oncol
January 2022
During the last decade, radiation oncology departments have integrated magnetic resonance imaging (MRI) equipment, procedures, and expertise into their practices. MRI safety is an important consideration because a large percentage of patients receiving radiation therapy have histories of multiple surgeries and implanted devices. However, MRI safety guidelines and workflows were traditionally designed for radiology departments.

To present a tumor motion control system during free breathing using direct tumor visual feedback to patients in 0.35 T magnetic resonance-guided radiotherapy (MRgRT). We present direct tumor visualization to patients by projecting real-time cine MR images on an MR-compatible display system inside a 0.

Purpose: To present lessons learned from magnetic resonance imaging (MRI) quality control (QC) tests for low-field MRI-guided radiation therapy (MR-IGRT) systems.
Methods: MRI QC programs were established for low-field MRI- Co and MRI-Linac systems. A retrospective analysis of MRI subsystem performance covered system commissioning, operations, maintenance, and quality control.
Article Synopsis
- MRI-guided radiation therapy was successfully used for the first time on a patient with an implantable cardioverter defibrillator (ICD) and a cardiac fibroma, involving 5 treatment sessions at 700 cGy per session.
- The treatment was administered with a 0.35 T MRI-linear accelerator that allowed for real-time tumor tracking, taking an average of 12.13 minutes per session.
- Key lessons included the importance of addressing MRI safety with ICDs, choosing effective tracking targets, and recognizing artifacts from the ICD that could affect tracking accuracy.
