Prospective Intestinal Ultrasound Study for Artificial Intelligence Algorithm Development

This observational study will use intestinal ultrasound images to help develop computer programs that may make it easier to assess bowel inflammation. The study will include adults who are healthy or who are having an intestinal ultrasound as part of care for inflammatory bowel disease, such as Crohn disease or ulcerative colitis. Researchers want to find out whether a computer program can measure bowel wall thickness from ultrasound images as accurately as experienced ultrasound clinicians. They will also explore whether the program can identify other changes in the bowel. Participants will have an intestinal ultrasound as part of their usual care. People who agree to take part will allow the research team to use de-identified ultrasound images and a small amount of related health information. No medication, experimental treatment, or additional ultrasound procedure will be given for this study. The computer program will not be used to make decisions about a participant's care, and participants will not receive individual results from the program.

Inclusion Criteria: * Adults aged 18 years or older. * Individuals who are either healthy with no known finding of inflammatory bowel disease before the ultrasound examination or undergoing intestinal ultrasound for inflammatory bowel disease screening, monitoring, or another clinical reason. * Individuals who are able and willing to provide informed consent for the collection and use of de-identified study data. Exclusion Criteria: * Individuals who do not meet the study demographic requirements. * Individuals unable or unwilling to provide informed consent. * Pregnant individuals. * Individuals with health conditions managed using drugs or medical-device intervention, or with unmanaged conditions or conditions requiring monitoring, that could affect study eligibility or the ultrasound assessment. * Individuals who have recently taken contrast-enhancing compounds.
