The first prescription was for 108.11 mCi and 114 mCi (105.73 percent) was successfully delivered. </br>The second prescription was for the right lobe, segment 4A using 13.51 mCi but only 10.04 mCi (74.32 percent) was able to be delivered. </br>The authorized user believes his patient reached stasis, so he halted the procedure per the Sirtex IFU (instructions for use).
