Table 1 Direct and indirect imaging features of adenomyosis
Imaging feature | Ultrasound description | MR description |
|---|---|---|
Direct features | Tiny myometrial cysts | Tiny myometrial cysts |
Hyperechoic nodules or striations | Myometrial foci of high signal intensity on T1-weighted images | |
Poor definition of the endometrial-myometrial interface | ||
Indirect features | Diffuse myometrial heterogeneity associated thin hypoechoic linear striations within a heterogeneous myometrium | Junctional zone thickening |
Abnormal myometrial signal intensity | ||
Diffuse asymmetric or symmetric widening of the myometrial walls | Large, regular, asymmetric uterus without leiomyomas |
