This trial investigates whether an ultrasound of the neck arteries can provide similar information to a CT scan of the heart for diagnosing blocked arteries in people with chest pain. Currently, CT scans are used but involve a small amount of radiation. The study will compare the…

This study tests a new 3D ultrasound probe to see tiny blood vessels inside fatty plaques in the neck arteries. These vessels can make plaques more likely to rupture and cause a stroke. Ten people who already had a standard ultrasound will get this new 3D scan with a contrast dye…

This study compares a new imaging technique called Texture and Colour Enhancement Imaging (TXI) with standard white light during colonoscopy in 219 people with inflammatory bowel disease (IBD). The goal is to see if TXI finds more dysplastic (precancerous) lesions. Each patient w…

This study compares two non-invasive tests for coronary heart disease: a CT scan of the heart arteries versus a stress ultrasound that also checks the neck arteries. The goal is to see which test better detects blockages and prevents heart attacks or other problems. 2,000 adults …

This trial compares two ways of inspecting the ileo-anal pouch during routine surveillance in adults with familial adenomatous polyposis (FAP): dye-based chromoendoscopy (spraying a blue dye) versus virtual chromoendoscopy (using special light filters). The goal is to see which t…
