Many current MR enterography protocols include axial and coronal 2D SSFP acquisitions, requiring multiple breath holds and often necessitating two doses of an antiperistaltic agent. We examine the feasibility of a single breath held coronal 3D SSFP acquisition with spatial resolution adequate for high quality axial reformatted views. Preliminary data in a small series of patients suggests that this technique generates images of excellent quality and may allow for a shorter and more efficient enterography protocol.
