At approximately 11 [MDT], the post administration measurements of the waste from the SIRSpheres Administration indicated that the activity administered to segment 2/3 of the patient's liver was only 68.7 percent of the prescribed activity. The written directive called for an activity of 0.24 GBq and residual waste activity measurements indicated that 0.165 GBq was delivered. The physician indicated that stasis was not reached during the administration to this segment. There was a separate administration to segment [four] of the liver in which stasis was reached.
