Multi Modal Imaging: An MRI Study to Investigate Differences in the Structure and the Function of the Brain at Rest.
United States165 participantsStarted 2011-03
Plain-language summary
The structural/RSN study involves Structural and Resting State Neuroimaging. The purpose of Structural Neuroimaging is to use MRI technology to identify cortical and white matter morphometric differences between patients with chronic pain conditions and healthy control subjects.
The purpose of the Resting State Neuroimaging study is to use functional MRI to identify possible disease related differences in various resting state networks in the brain.
In addition we are looking at the effect gut microbiota on brain function in healthy and IBS participants.
The overall goal is to identify structural and functional brain differences in persons with chronic pain conditions such as Irritable Bowel Syndrome (IBS, Cyclical Vomiting Syndrome(CVS) and vestibulodynia/vulvodynia. We are also looking at Inflammatory Bowel Disease(ulcerative colitis and Crohn's disease. We will be comparing differences between these conditions and matched healthy control subjects.

Exclusion criteria
✕. Evidence of structural abnormality of the gastrointestinal tract. Subjects with Functional GI conditions must be without 'red flags', that may indicate gastrointestinal disease. Exclusionary GI conditions include but are not limited to: gastrointestinal surgery (exceptions: IBD group, appendectomy, benign polypectomy, cholecystectomy)also esophagitis, celiac disease, gastrointestinal malignancy or obstruction; peptic, duodenal or gastric ulcer disease.
✕. Clinical evidence of cardiovascular, respiratory, renal, hepatic, malignancy, hematologic, neurologic, psychiatric or any disease that the PI determines may interfere with safe participation in the study
✕. Use of investigational drugs, products or devices within 28 days prior to screen and through study participation.
✕. Subjects with current regular use of narcotics and or opioids. Use of medications/drugs that affect the central nervous system. TCA's, SSRI's or other antidepressants are allowed if on stable dose for 3 months or more.
✕. Pregnancy or breast feeding
✕. Subjects with extreme obesity (BMI \> 35%)
✕. Subjects with metal implants, dental retainers, large tattoos (e.g. full arm or back) or claustrophobia; making MRI safety not possible.
