Performance Evaluation of a 3D PSIR Sequence in MRI at 1.5T (ESPOIR1-5)

December 12, 2023 updated by: Fondation Ophtalmologique Adolphe de Rothschild

Performance Evaluation of a 3D PSIR Sequence in MRI at 1.5T in the Detection and Characterization of Spinal Cord Injuries in Patients With Multiple Sclerosis

Inclusion visit (D0):

  • verification of inclusion and non-inclusion criteria
  • information and collection of consent
  • standard imaging protocol prescribed as part of the usual treatment: sagittal T1 and T2 slices after injection of contrast product (Gadolinium), o 3D STIR sequence.
  • 3D PSIR sequence at the level of the cervical cord for the duration of the additional sequence is 10 minutes, for a total examination time of 45 minutes (instead of 35 minutes).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study will be offered prospectively to patients presenting to the imaging department for a 1.5T MRI for bone marrow exploration, in the context of inflammatory involvement of the nevrax

Description

Inclusion Criteria:

  • Patient over 18 years old
  • To benefit from a medullary exploration planned by MRI 1.5T as part of a first evaluation or a re-evaluation of inflammatory involvement of the nevrax
  • Express consent to participate in the study
  • Affiliate or beneficiary of a social security scheme

Exclusion Criteria:

  • Patient benefiting from a legal protection measure
  • Pregnant, parturient or breastfeeding woman
  • Absolute or relative contraindication to MRI

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Estimate the number of spinal cord injuries detected with the set of standard sequences (T1, T2 and STIR) that are not detected with the 3D PSIR sequence
Time Frame: 1 DAY
1 DAY
Estimate the number of active lesions taking the contrast after injection of gadolinium, with the 3D PSIR sequence which is not detected in the set of standard sequences (T1, T2 and STIR)
Time Frame: 1 day
1 day
Compare the diagnostic confidence expressed by the radiologist for the detection of spinal cord injuries with the 3D PSIR sequence compared to the set of standard sequences (T1, T2 and STIR)
Time Frame: 1 DAY
1 DAY
Describe the quality of the images in terms of artifacts for each of the sequences used (T1, T2, STIR and PSIR)
Time Frame: 1 DAY
1 DAY
Measure the signal-to-noise ratio of each of the sequences used (T1, T2, STIR and PSIR)
Time Frame: 1 DAY
1 DAY
Measure the inter-observer agreement on the number of lesions detected with the 3D PSIR sequence
Time Frame: 1 DAY
1 DAY
Measure the intra-observer agreement on the number of lesions detected with the 3D PSIR sequence
Time Frame: 1 DAY
1 DAY

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 6, 2021

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
