#1Stereotactic radiosurgery is a high precision treatment for tumors in the brain. Since the target volume for treatment is defined on MR images, the spatial fidelity of these images is of critical importance.While many institutes to date offer SRS treatments, guidelines and criteria for MRI and CT geometrical fidelity are currently lacking.Many institutions have their MR images acquired within their diagnostic radiology departments. As spatial fidelity if of less concern for diagnostic purposes, the diagnostic MR images may suffer from geometric distortions.Evaluating the variability in spatial fidelity across practices, potential impact on delivered treatment and identifying common sources of geometric distortion will help determine whether this concern should be priority for the community and generate data for the development of recommendations.
We would like to share the following survey from the International Gamma Knife Research Foundation (IGKRF) to inform on the practice patterns of patients treated with radiosurgery for brain metastases. Please use the link below to complete the IGKRF online survey with 27 short questions, which should take 5-10 minutes to complete.[More information]
Please also forward this to your center's practicing clinicians that are involved in the radiosurgical management of patients with brain metastases (i.e. Neurosurgeons, Radiation Oncologists, Medical Physicists, Neuro-Oncologists, Medical Oncologists as appropriate).
