Magnetic resonance (MR) imaging with cine mode display can evaluate uterine contractility during menstruation. Uterine changes seen on MR imaging correlate with primary dysmenorrhea pain severity.

Area of Science:

  • Reproductive medicine
  • Medical imaging
  • Gynecology

Background:

  • Primary dysmenorrhea significantly impacts women's quality of life.
  • Understanding uterine contractility during menstruation is crucial for diagnosing dysmenorrhea.
  • Non-invasive imaging techniques are needed to assess uterine function.

Purpose of the Study:

  • To prospectively evaluate uterine contractility during menstruation using magnetic resonance (MR) imaging.
  • To investigate the relationship between uterine contractility and primary dysmenorrhea.
  • To assess the utility of cine-mode MR imaging in evaluating dysmenorrhea.

Main Methods:

  • Nineteen healthy women underwent MR imaging during menstrual cycle days 1-3.
  • Cine-mode MR imaging captured uterine activity every 3 seconds for 3 minutes.

  • Analysis included myometrial layer thickness, endometrial distortion, uterine peristalsis, and myometrial area.

    • Main Results:

    • MR imaging revealed significant uterine changes during early menstruation.
    • Inner myometrial layer thickness and endometrial distortion correlated with pain severity (P < .001).
    • Uterine myometrial area decreased significantly in women with dysmenorrhea compared to controls (P = .010).

    Conclusions:

    • Uterine MR imaging features on cycle days 1-3 correlate with dysmenorrhea pain.
    • Cine-mode MR imaging is a promising tool for evaluating primary dysmenorrhea.
    • This technique offers objective insights into uterine contractility in dysmenorrhea.
