Evaluation of Diffusion Tensor Imaging and High Frequency 3D Endovaginal Ultrasound (EDITUS)
Evaluation of Diffusion Tensor Imaging and High Frequency 3D Endovaginal Ultrasound (EVUS) in Understanding the Anatomy of the Pelvic Floor and Levator Ani Muscle Injury.

Detailed Description
The study population is females with symptoms of pelvic floor dysfunction, and with suspected anatomical abnormalities of the pelvic floor muscles, for example following obstetric injury. The participants will be recruited to the study through Pelvic Floor and gynaecology Clinics. Each patient will undergo the same imaging investigations, pelvic floor MRI and three-dimensional high frequency internal ultrasound. As the MRI is regarded the gold standard examination in the assessment of the levator ani muscle (LAM), it will be used as reference in our study. A novel technique in MR imaging, which allows tracking of the pelvic floor muscle fibers, Diffusion Tensor Imaging (DTI) will be performed in addition to the standard scanning protocol. The investigator thinks that MRI with DTI is superior to routine MRI in visualization of LAM.
Moreover, every participant will undergo pelvic floor ultrasound (EVUS), which is believed to be comparable with routine MRI in diagnosis of LAM defects. The investigator hypothesize that this type of ultrasound is not inferior to MRI with DTI in visualizing pelvic floor muscles and their abnormalities.
All images will be assessed independently by two radiologists experienced in pelvic floor imaging, who will not be aware of each other's findings.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: MRI including DTI
MR imaging will be performed on 3T MRI scanner (Skyra, Avanto) in supine position with no rectal contrast. The patients will undergo pelvic MRI with additional diffusion tensor (DTI) sequences dedicated for assessment of the fibres in the pelvic floor muscles. DTI will be processed with the use of special software. The images will be assessed separately by two clinicians who will not know patients' symptoms or results of the US. |
A novel technique in MR imaging, which allows tracking of the pelvic floor muscle fibers, Diffusion Tensor Imaging (DTI) will be performed in addition to the standard scanning protocol.
We think that MRI with DTI is superior to routine MRI in visualization of LAM.
The patient will be scanned in a supine position and the probe is inserted into the vagina in the neutral position to avoid excessive pressure on surrounding structures to avoid distortion of the anatomy. The 3D data automatic acquisition takes approximately 70 seconds. The analysis of the ultrasound images will be performed on the Trust computers by Radiologists experienced in pelvic floor ultrasound. Participant will be asked to complete a VAS score for the US. |
Active Comparator: Pelvic floor ultrasound.
Internal pelvic floor ultrasound will be performed with the use of high-frequency transducers with automatic 3D image acquisition by one of the Consultant Radiologists involved in the study. No preparation is required. No vaginal or rectal contrast is used. The patient will be scanned in a supine position and the probe is inserted into the vagina in the neutral position to avoid excessive pressure on surrounding structures to avoid distortion of the anatomy. The 3D data automatic acquisition takes approximately 70 seconds. The analysis of the ultrasound images will be performed on the Trust computers by Radiologists experienced in pelvic floor ultrasound. |
