Official Title: Investigation of Diffusion Tensor Imaging Magnetic Resonance Imaging (DTI MRI) as a Correlate to Pain Relief and Facial Numbness in Patients Following Stereotactic Radiosu
Brief Summary: Trigeminal neuralgia or tic douloureux is severe, often debilitating, facial pain that significantly impairs the patient's quality of life and health. Stereotactic radiosurgery has been shown to provide pain relief in majority of patients treated. However, a common side effect of radiosurgery is facial numbness. To better understand how radiosurgery can bring about pain relief and facial numbness, we are conducting a study in which brain MRI scans will be done following stereotactic radiosurgery to learn if there are any changes in the MRI scans that correlate with symptoms.
