MR enterography is the modality of choice for the imaging of inflammatory bowel disease, but presents unique challenges in the pediatric population, particularly with respect to motion degradation. Variable refocusing flip angle single shot fast spin echo (vrfSSFSE), an improvement upon the traditional single shot fast spin echo (SSFSE) sequence, allows for shortened acquisition times and improved contrast and spatial resolution. Clinical use of vrfSSFSE in pediatric MR enterography has led to subjective improvements in image quality and has allowed for improved identification of many imaging findings related to inflammatory bowel disease.
