How is adenomyosis diagnosed?

A doctor may consider a diagnosis of adenomyosis based on signs and symptoms. An ultrasound and even magnetic resonance imaging (MRI) can be used to visualize the uterus. The most definitive diagnosis, however, is accomplished by looking at the cells under a microscope after complete removal of the uterus has been done.
Most commonly adenomyosis is discovered incidentally when the uterus is surgically removed for other reasons. While it can be diagnosed during hysterosalpingography (HSG) where contrast dye is injected in to the uterine cavity or with pelvic ultrasound (US), magnetic resonance imaging (MRI) is the best imaging study to detect adenomyosis.
