*** types of MRI artifacts,including acquisition and preprocessing errors,were simulated to test a machine learning brain tumor segmentation model for potential failure ***-world medical deployments of machine learning algorithms are less common than the number of medical research papers using machine *** of the gap between the performance of models in research and deployment comes from a lack of hard test cases in the data used to train a *** failure modes were simulated for a pretrained brain tumor segmentation model that utilizes standard MRI and used to evaluate the performance of the model under *** simulated MRI artifacts consisted of motion,susceptibility induced signal loss,aliasing,field inhomogeneity,sequence mislabeling,sequence misalignment,and skull stripping *** artifact with the largest effect was the simplest,sequence mislabeling,though motion,field inhomogeneity,and sequence misalignment also caused significant performance *** model was most susceptible to artifacts affecting the FLAIR(fluid attenuation inversion recovery)***,these simulated artifacts could be used to test other brain MRI models,but this approach could be used across medical imaging applications.
