Feed and Wrap Magnetic Resonance Urography Provides Anatomic and Functional Imaging in Infants without Anesthesia

Abstract Objective To describe a technique for performing Magnetic Resonance Urogram (MRU) in infants without sedation or anesthesia. Methods Eighteen infants underwent MRU in the absence of sedating medications using a ‘feed and wrap’ technique (FW-MRU). Dynamic contrast enhanced images were obtained. Dynamic radial VIBE (DRV) and compressed sensing (CS) image reconstruction were used to correct for motion artifact. Results Seventeen of the 18 patients had successful FW-MRU. FW-MRU provided high-quality anatomic and functional renal data. Conclusion Initial experience with FW-MRU demonstrates it to be a promising anesthesia-free modality for obtaining anatomic and functional imaging of the urinary tract in infants.
