PURPOSE: Intraoperative ultrasound (iUS) is a valuable tool-inexpensive, adds minimal surgical time, and involves minimal risk. The diagnostic predictive value of iUS is not fully characterized in Pediatric Neurosurgery. Our objective is to determine if surgeon-completed iUS has good concordance with post-operative MRI in estimating extent of surgical resection (EOR) of pediatric @entity1313 . METHODS: We reviewed charts of all pediatric @entity1313 resections (single institution 2006-2013). Those with iUS and postoperative imaging (<1 week) were included. The surgeon's estimation of the EOR based on iUS and the post-operative neuroimaging results (gold standard) were collected, as well as information about the @entity1 / @entity5 . RESULTS: Two hundred two resections were reviewed and 58 cases were included. Twenty-six of the excluded cases utilized iUS but did not have EOR indicated. The concordance of interpretation between iUS and post-operative MRI was 98.3%. Of 43 cases where iUS suggested gross total resection, 42 were confirmed on MRI (negative predictive value (NPV), 98%). All 15 cases where iUS suggested subtotal resection were confirmed on MRI (positive predictive value ( @entity2286 ), 100 %). Agreement between iUS and post-operative imaging had an overall Kappa score of 0.956, signifying almost perfect agreement. CONCLUSION: The results from this study suggest that iUS is reliable with both @entity41 ( @entity2286 -100%) and when it suggests no residual (NPV-98%) in @entity5 that are easily identifiable on iUS. However, @entity5 that were difficult to visualize on iUS were potentially excluded, and therefore, these results should not be extrapolated for all @entity1313 types.
