What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new, non-invasive MRI method to measure oxygen levels in the portal vein, which carries blood from the gut to the liver. Researchers will compare 20 people with meal-related abdominal pain due to narrowed gut arteries (chronic mesenteric ischemia) to 20 people with similar narrowing but no pain. The goal is to see if this MRI can accurately diagnose the condition without radiation or invasive procedures.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this MRI method could provide a safe, radiation-free way to diagnose chronic mesenteric ischemia, reducing the need for invasive tests.
What could go wrong
This is a small, early-stage study with only 40 participants. The MRI method may not prove accurate enough for routine diagnosis, and results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * \- Written informed consent * Male or female persons \> 18 years * Subjects with postprandial abdominal pain considered compatible with mesenteric ischemia, and severe stenosis of the SMA and eventually other mesenteric arteries, diagnosed with CT-angiography or Doppler ultrasound * OR subjects with severe stenosis of the SMA and eventually other mesenteric arteries, diagnosed with CT-angiography or Doppler ultrasound, but not postprandial pain Exclusion Criteria: * \- Serious concurrent illness * BMI \> 30 * Cardiac arrhythmia * Anemia with Hgb \< 7,0 mmol/l * Pregnancy or breastfeeding (urine HCG is performed on all fertile women) * Systolic blood pressure \< 90 or \> 200 mmHg * Claustrophobia * Patients who, in the judgement of the investigator, is incapable of participating * Metallic foreign objects in the body, or pacemakers
