Junctional zone

Junctional zone is a region representing the inner myometrium and is a very important imaging feature in pelvic MR imaging for interpretation of various pathologies. In its intact state, it is usually visualised as a low T2 signal layer beneath the endometrium.

This low signal intensity is thought to be from closely packed compact smooth muscle cells with little extracellular matrix and water content.

Disruption or alteration of the junctional zone with various pathological conditions.

Some research also emphasises the use of the junctional zone as a predictor for implantation failure after in vitro fertilisation 2.
