This table provides additional information on the observed distributions of Facility Reference Levels (FRLs). The National DRLs are shown in bold. Rounded 25th and 50th percentiles of the FRL distributions are also shown. This additional information can be used by a facility to more fully appreciate how their FRLs compare to those of their peers. If your FRL is near the 50th percentile you are approximately consistent with most other sites. If your FRL is below the 25th percentile you are amongst the lowest dose sites. It is important to ensure that image quality is sufficient for the clinical task.
