Pilot Study of Measurement Agreement Between Morphological and Diffusion Tensor Imaging MRI for Pelvic Nerve Cartography

NCT03320343 | Completed

• 1 other identifier: NIMAO/2017-01/MB-01
• Study Type: observational
• Target: 20
• Locations: 1 country
• Sites: 1

Brief Summary

The investigators hypothesize that diffusion tensor imaging (DTI) will produce a similar map of autonomic pelvic innervation to that obtained using 3D morphological MRI sequences

Conditions

Pelvic MRI

Outcome Measures

Primary Outcomes (3)

• Agreement between DTI imaging measures versus 3D morphological MRI measures for point of penetration of the pelvic splanchnic nerves in the lower hypogastric plexus

  Lin's concordance correlation coefficient and Bland-Altman Plot

  Day 0

• Agreement between DTI imaging measures versus 3D morphological MRI measures for origin of the cavernous nerves

  Lin's concordance correlation coefficient and Bland-Altman Plot

Study Population

All patients admitted to the Medical Imaging Department of the CHU Nîmes for an MRI examination of the pelvic region for any reason

You may qualify if:

• The patient must have given their free and informed consent and signed the consent form
• The patient must be a member or beneficiary of a health insurance plan
• The patient it at least 18 years old
• The patient has been admitted for an MRI examination of the pelvic region, for any reason

You may not qualify if:

• The subject refuses to sign the consent
