Contour ProtégéAI+ can produce incorrect or implausible segmentations when the underlying anatomy is in the field of view of the scan but not clearly discernable due to image quality, noise, or the generally low contrast of some structures. This can occur in any situation where the organ at risk is not clearly discernable in the image. While both images with and without IV contrast are represented in the training set for Contour ProtégéAI+, the effect of iodinated contrast can vary due to patient weight, contrast dosage, and time since injection. In cases where this is unusually intense brain or kidney enhancement, the posterior boundary can be incorrectly segmented. The age breakdown of the training data, where patient age was available, was predominantly in the 40-60 and 60+ ranges. While this is appropriate to the intended patient populations, only a small proportion of testing and training data was for patients under 40, so more intensive review may be warranted for younger patients.
