The good and bad of MRI evaluation of the urothelial tract
When performed properly, MR urography (MRU) can be an alternative to CT urography (CTU) for imaging of the entire urinary tract. Some radiologists may prefer MRU for pediatric populations, patients undergoing repeat examinations, and individuals with compromised renal functions.

However, MRU can be a challenging examination to perform and interpret; therefore, a team of researchers published a study outlining the pitfalls along with potential methods of correcting, detecting, or avoiding them. The information is discussed in the study, "MRI Evaluation of the Urothelial Tract: Pitfalls and Solutions," published in the December 2016 issue of the American Journal of Roentgenology (AJR)....
