Colonic dysmotility is very common and requires non-invasive/point-of-care diagnostic methods in both children and adult care. We are developing an assessment of human colonic motor patterns, the biomarkers of colon motility, via non-invasive ultrasound, providing anatomical, neurogenic and myogenic features of colon motor patterns.
What is ultrasound?
Medical ultrasound is a diagnostic technique to create images of internal organs. The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography. Here we generate videos of large intestine (colon) movements, to see if the characteristic motor patterns are normal.
- Adults aged 18 - 95
- Healthy volunteers and patients with chronic refractory constipation
What the study involves
Patients will receive abdominal ultrasound scanning to capture movements of the colon. The videos thus recorded are analyzed via sophisticated spatiotemporal mapping techniques that we are developing.
One or more sessions of 2 hours
We will provide parking reimbursement and financial compensation per hour.
