Abstract:
|
One of the problems in nuclear medicine is recognizing obstruction in the kidney. The first stage is to determine whether a diuretic is needed. If it is not needed, the kidney is not obstructed. If it is needed, the second stage is to determine whether the kidney is obstructed. The goal is to identify covariates that predict kidney obstruction. A naive approach is to develop a two-stage model based on ROC curve methodology. In this presentation, we present an alternative method, and we compare this method with the naive approach.
