Title: | Junctional zone thickness in young nulliparous women according to menstrual cycle and hormonal contraception use | Authors: | MEYLAERTS, Liesbeth Wijnen, Leen Grieten, Martijn PALMERS, Yvan OMBELET, Willem VANDERSTEEN, Marjan |
Issue Date: | 2017 | Publisher: | ELSEVIER SCI LTD | Source: | REPRODUCTIVE BIOMEDICINE ONLINE, 34(2), p. 212-220 | Abstract: | This prospective study aims to determine the optimal menstrual phase and uterine location to detect the thickest junctional zone by magnetic resonance imaging (MRI). Healthy nulliparous women were subdivided according to their use of hormonal contraception. Each women was investigated three times during their menstrual cycle. Eighteen nulliparous non-users and 29 nulliparous users of hormonal contraception (mean age 26.4 and 25.8 years, respectively) underwent a pelvic MRI (1.5T) examination during the follicular, ovulatory and luteal phase. The junctional zone thickness was measured at six locations in the uterine wall. A significantly thinner junctional zone was observed at the anterior and posterior wall of the midcorpus (P = 0.01 and P = 0.004 respectively) and fundus (P = 0.009 and P = 0.023 respectively), in the contraception users compared with the non-users. No differences in junctional zone thickness were noticed between the menstrual phases and the uterine wall locations. The ratio of junctional zone versus total myometrial thickness was also different between both groups and between the assessed uterine locations. To conclude, any phase in the menstrual cycle and location within the uterine wall was validated to determine the junctional zone thickness on MRI, although the fundal location is preferred. | Notes: | [Meylaerts, Liesbeth Johannes; Wijnen, Leen; Grieten, Martijn; Palmers, Yvan] Ziekenhuis Oost Limburg, Dept Med Imaging, Schiepsebos 6, B-3600 Genk, Belgium.
