Table 1: Dose comparison between TBI and TMI planning for a prescribed dose of 11 Gy.

A) The mean delivered dose to target (bone marrow, spleen) and organs (lungs, gut and liver) was determined for the TBI, TMI I and TMI I+4 treatment plans. The % reduction in dose delivered was calculated using the TBI-delivered dose to the respective organs as reference. There was a significant reduction of dose delivered to lung, liver and gut; however, dose delivered to bone marrow was similar between TBI, TMI I and TMI I+4 plans. B-D)The D95 (B), D80 (C), and D5 (D) for bones and other vital organs for TBI, TMI I and TMI I+4 plans. The dose values ± s.d was calculated for n=5 mice/group.
