Uterine DTI was performed for nine healthy young women on a 3T scanner. VOIs were drawn for the outer myometrium (OM), junctional zone (JZ) and endometrium (EM). ADC, FA and maximum fiber length were compared. Fibers were classified into 12 groups and visually evaluated. ADC was highest for OM (1.12), followed by EM (0.97) and JZ (0.83). FA was highest for JZ (0.297), followed by OM (0.257) and EM (0.186). Fibers were longest in OM (42.0mm), followed by JZ (34.2mm) and EM (20.0mm). Circular orientation was observed in 50% (36/72) of fibers in OM and in 44% (32/72) in JZ.
