Translabial Three-Dimensional Ultrasonography Compared With Magnetic Resonance Imaging in Detecting Levator Ani Defects

Abstract

Netherlands Trial Register, www.trialregister.nl, NTR2220.

How does 3D endovaginal ultrasound compare to magnetic resonance imaging in the evaluation of levator ani anatomy?

“…The main difference between our study and Notten et al 10 is that by the virtue of the fact that EVUS places a 16 MHz transducers millimeters away from the LAM, it can see much more detail than either MRI or translabial US. Furthermore, translabial/transperianeal ultrasound studies use terms puborectalis, pubococcygeus and levator ani interchangably because of the lack of definition.…”

“…9,10 Translabial 3D US has been compared with MRI and showed reasonable agreement with MRI in detecting puborectalis defects. 10 Based on our literature review on PubMed and Ovid database for the key words ''Ultrasound'' and ''MRI'' from 1965 till 2015, we did not find any publication on comparison of 3D Endovaginal Ultrasound and MRI. In the current study, we sought to compare MRI to 3D Endovaginal US in the evaluation of LAM defects in women with pelvic floor disorders.…”

“…EVUS has been shown to reliably visualize the levator ani anatomy and there are studies comparing translabial 3D US to MRI in evaluation puborectalis avulsions . Translabial 3D US has been compared with MRI and showed reasonable agreement with MRI in detecting puborectalis defects .…”

Comparison of translabial three-dimensional ultrasound with magnetic resonance imaging for measurement of levator hiatal biometry at rest

“…The present study used data obtained in the TRUDIL study, in which the validation and clinical relevance of translabial 3D ultrasound for diagnosing levator ani defects were investigated in women with POP. The TRUDIL study was a multicenter prospective cohort study performed in nine hospitals in The Netherlands.…”

Recurrence risk is associated with preoperatively advanced prolapse stage: Is there a difference between women with stage 2 and those with stage 3 or 4 cystocele?

“…In the second study, women were recruited from June 2010 until November 2012, with a follow-up of 1 year. The primary aim of this study was to assess the diagnostic accuracy of translabial 3D US in the diagnosis of levator defects in women with POP, using magnetic resonance imaging (MRI) as reference test [16, 17]. The protocols of both studies were approved by the medical ethics committees of each participating hospital, and all women gave written informed consent before enrollment in the study.…”
