Comparison of sacrum uptake according to bone marrow involvement

Bone marrow involvement Negative BM (23 patients) Up to 25% BM involvement (5 patients) >25% BM involvement (10 patients) p-value* p-value**
Sacrum uptake 24h Mean 1.31 Mean 1.432 Mean 1.93 0.18 0.18
Median 1.1 Median 1.2 Median 1.75
Range 0.5-3.8 Range 0.76 – 2.6 Range 0.8-4
Sacrum uptake 48h Mean 1.24 Mean 1.66 Mean 2.237 0.018 0.005
Median 1.1 Median 1.3 Median 2.4

BM, bone marrow

*

p-values represents comparisons between the group with no bone marrow involvement and >25%.

**

p-values represents comparison between the group with no bone marrow involvement versus any bone marrow involvement (i.e., all 15 patients with positive bone marrow).
