Radiation necrosis is one of the most feared complications of stereotactic radiosurgery.  With increasing utilization of stereotactic radiosurgery, the incidence of radiation necrosis is also increasing.  Historically, diagnosis had been difficult since surgery or biopsy is not often done and imaging had been imperfect.  More recently, however, perfusion MRI has emerged as helpful modality to help distinguish radiation necrosis from tumor recurrence.  There are other promising modalities currently being investigated, including amino acid PET and radiomics.  Steroids and surgery had been the treatment of choice, but more recently, bevacizumab and laser interstitial thermal therapy have emerged as excellent treatment options for radiation necrosis.  Due to better diagnostic and treatment options, perhaps radiation necrosis should be less feared.  This webinar will review the diagnosis and treatment of radiation necrosis, and discuss future investigations.

Tremor is amongst the most prevalent neurological conditions and often refractory to medical therapy. While brain stimulation is an effective therapy, a resurgence of interest in ablation requires us to appreciate the success of radiosurgical thalamotomy, the technical and imaging advances that have advanced this treatment, and the opportunities to further enhance safety and efficacy.
