[Abstract] Objective: To study different DTI characteristics among uterine fibroids with different T2 signals.Materials and Methods: Clinical cases were collected from April 2014 to January 2015, including 116 patients with 141 uterine fibroids, grouped by T2WI signal intensity as below: hypointense group (57), isointense group (33) and hyperintense group (51). All the patients underwent routine MR plain scan, enhanced scan and DTI examination. Compared all DTI characteristics from each group, test and analyzed the MD value, FA value and RA value with the SPSS 19.0 software.Results: The MD value of hypointense group was significantly lower than that of isointense group and hyperintense group (P=0.000, 0.000), while the MD value of isointense fibroids group was significantly lower than hyperintense group (P=0.000). To compare the FA and RA value between three groups, the hypointense group is significantly higher than isointense and hyperintense group (P=0.000, 0.000), and the isointense group is higher than hyperintense group (P=0.000). RA value of each group had the similar changing trend with the FA value, and lower than FA value, such as the hypointense group is higher than isointense and hyperintense group (P=0.000, 0.000), and the isointense group is higher than hyperintense group (P=0.000), there were significant difference in three groups.Conclusion: Uterine fibroids with different T2 signals intensity have different characteristics in DTI imaging, and DTI parameters can be reflected in the different organizational structure of fibroids.
