[Abstract] Objective: To observe the DTI characteristics of uterine fibroids with homogeneous hypointense signal on T2WI, including the comparison with normal muscle layers, and the difference of DTI parameters between fibroids at different location.Materials and Methods: Sixty-five patients with uterine fibroids were performed routine MRI scanning, enhanced scanning and DTI scan. Eighty uterine leiomyomas were analyzed, including 42 intramural hysteromyoma and 38 subserous fibroids. The fractional anisotropy (FA), mean diffusivity (MD) and relatively anisotropy (RA) of all lesions and normal muscle layers were calculated, all data were analyzed through Independent-Samples t test by SPSS 19.0.Results: MD values of hysteromyomas with homogeneous hypointense signal on T2WI was (1.275±0.204)×10-3 mm2/s, which was significantly lower than the myometrium, FA values (0.465±0.114) and RA values (0.420±0.110) were higher than the myometrium, but there was no significant difference between the parameters of subserous fibroids and intramural hysteromyoma.Conclusions: The DTI characteristics of uterine fibroids with homogeneous hypointense signal on T2WI had some characteristics, which were different with the normal muscle layer, and the location of hysteromyoma did not have much effect on the characteristics of DTI.
