The emergency department (ED) at Rhode Island Hospital is essentially a hospital within a hospital. Rhode Island Hospital’s ED is one of the largest emergency departments in the country with more than 101,000 visits per year. Our Andrew F. Anderson Emergency Center, which is a Level I trauma center, is equipped with five x-ray units within the five trauma rooms. Three additional x-ray units, two ultrasound rooms, two 64-slice CT scanners and a new MRI unit complete the imaging resources.
