Stereotactic radiosurgery (SRS) is one of the least invasive treatments for @entity4254 ( @entity4254 ). To date, most reports have been about @entity1953 -based treatments (i.e., Gamma Knife) with limited data on image-guided stereotactic linear accelerator treatments. We describe our initial experience of using BrainLAB Novalis stereotactic system for the radiosurgical treatment of @entity4254 . A total of 20 @entity1 were treated between July 2004 and February 2007. Each SRS procedure was performed using the BrainLAB Novalis System. Thin cuts MRI images of 1.5 mm thickness were acquired and fused with the simulation CT of each @entity1 . Majority of the @entity1 received a maximum dose of 90 Gy. The median brainstem dose to 1.0 cc and 0.1 cc was 2.3 Gy and 13.5 Gy, respectively. In addition, specially acquired three-dimensional fast imaging sequence employing steady-state acquisition (FIESTA) MRI was utilized to improve target delineation of the trigeminal proximal nerve root entry zone. Barrow Neurological Index (BNI) @entity158 scale for @entity4254 was used for assessing treatment outcome. At a median follow-up time of 14.2 months, 19 @entity1 (95%) reported at least some improvement in @entity158 . Eight (40%) @entity1 were @entity158 -free and stopped all medications (BNI Grade I) while another 2 (10%) @entity1 also stopped medications but reported occasional @entity158 (BNI Grade II). Another 2 (10%) @entity1 reported no @entity158 and 7 (35%) @entity1 only occasional @entity158 while continuing medications, BNI Grade IIIA and IIIB, respectively. Median time to @entity158 control was 8.5 days (range: 1-70 days). No @entity1 reported severe @entity158 , worsening @entity158 or any @entity158 not controlled on their previously taken medication. Intermittent or persistent @entity1183 following treatments occurred in 35% of @entity1 . No other complications were reported. Stereotactic radiosurgery using the BrainLAB Novalis system is a safe and effective treatment for @entity4254 . This information is important as more centers are obtaining image-guided stereotactic-based linear accelerators capable of performing radiosurgery.
