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
