Description: An outcome prediction system has been designed that can model the effect of multiple Arteriovenous Malformation (AVM) prognostic factors on stereotactic radiosurgical outcome. This system is adaptive allowing refinement in outcome predictions with the accrual of patient data. Bayesian network models (Naive Bayes, Tree Augmented Naive Bayes, Chow Liu and Domain Knowledge based) were trained on a data set containing information on 202 patients who underwent radiosurgery at Sunnybrook hospital in Toronto. These trained models form the core of the system and their predictions can be subsequently updated as new patient data is acquired. Additional system features include the provision of an electronic patient record for data collection. Variable dependency diagrams output by the system aid in disease understanding. As well, validation tools built into the system permit assessment of prediction accuracy over time. This thesis also outlines the results of analyzing quality of life data of AVM patients undergoing radiosurgery.
