title: MR imaging of retained products of conception.
abstract: OBJECTIVE
  The objective of this article is to describe the MR imaging appearances of retained products of conception.
  
  
  CONCLUSIONS
  Retained products of conception appear on MR imaging as an intracavitary uterine soft-tissue mass with variable amounts of enhancing tissue and variable degrees of myometrial thinning and obliteration of the junctional zone. These findings should not be misinterpreted as indicating gestational trophoblastic disease, particularly in the setting of a postpartum patient with a normal or minimally elevated beta-human chorionic gonadotropin level. MR imaging may also be helpful in showing anatomic variants that hinder successful instrumentation of the uterine cavity in patients with suspected retained products of conception.
