Imaging modalities to determine ventriculoperitoneal shunt malfunction

Use of sequential vs. simultaneous testing with low-risk modalities should be considered for optimal benefit while minimizing radiation risk for this vulnerable population. Overall, we illustrate that within the paucity of data that exists to evaluate imaging modalities in the evaluation of VP shunt failure, there are stark characteristic differences between the available studies in age ranges, gender composition, sample size, and study type.
