Other imaging findings include colour doppler, sonohysterography, hysterosalpingography, and nuclear imaging (PET scan). These imaging modalities have proven useful for diagnosing polyps, endometrioma’s and adenomyosis.

Color doppler is a type of ultrasound that visualizes flow direction and velocity.^[1]

• This study can be done to diagnose endometrial polyps where it shows a single feeding vessel extending to and supplying the polyp^[2]

Sonohysterography is an ultrasound technique used to asses the uterine anatomical structure. It is most commonly utilized for purposes of assessing fertility.^[3]

• Sonohysterography may be helpful in determining endometrial polyps which presents echogenic, smooth masses outlined by fluid^[4]

• This study can be done to diagnose:
  • Endometrial polyps: may present as pedunculated masses on imaging^[5]
  • Adenomyosis: diverticula extending into the myometrium^[6]

• PET-CT may be done to detect uterine malignancies but it is less accurate than MRI and ultrasounds^[7]
