Abstract

Objective To investigate the feasibility of Mapping T2* imaging in the evaluation of the feasibility of the bone marrow of the bone marrow. Methods Mapping T2* imaging was performed on 30 cases of young volunteers with MR 16 echo GRE sequence of L5, and the T2* values of bone marrow T2* were measured in the upper and lower regions of the sacral region and the lower end of the L5. Results The mean value of T2* in the iliac side of the di joint was 23.08+2.9ms sacral 21.09+3.43ms, iliac bone marrow T2* in the sacral side (P<0.05); L5 vertebral endplate bone marrow T2* values is 18.55+5.5ms, respectively less than iliac and sacral bone marrow side T2* values (P<0.05); and the left iliac bone area (ri1/RS1 LI4/Ls4 ri1/LI4 RS1/Ls4) T2* values compared to no difference (P>0.05), left and right sacrum region (RI2/RS2 Li3/Li3, Li3/RI2 LS3/ RS2 T2* value contrast is also no statistical significance (P>0.05). Conclusion The bone marrow of normal young people with the bone marrow contains more than the sacral side, and the iliac and sacral sides are more than the lower end of the L5 vertebral body. T2* mapping imaging technique is feasible for the evaluation of the content of the bone marrow
