The results of our study demonstrate a wide range of interpretation, with wider ranges observed in more complex cases and with vague clinical complaints. Comparison to the primary reader required the use of aggregate analysis and an agreement percentage cutoff to minimize bias and the limitations of this type of study. An intensive evaluation of radiologist performance such as this could be considered in various settings such as a quality assurance program, intense scrutiny of an individual radiologist whether competency is in question, or for medicolegal purpose to ascertain standard of care.
