To determine tumor volume changes in terms of radiological response in patients with meningioma treated with Gamma Knife Radiosurgery and to analyze the relationship between Total Tumor Volume and Diffusion Tensor Imaging parameters, it is investigated whether the response to treatment can be predicted by pre-radiosur surgery DTI findings.
Objective: This study was conducted to determine tumor volume changes in terms of radiological response in patients with meningioma treated with Gamma Knife Radiosurgery (GKR) and to analyze the relationship between Total Tumor Volume (TTV) and Diffusion Tensor Imaging (DTI) parameters. In addition, we investigated whether the response to treatment can be predicted by pre-radiosurgery DTI findings.
