ABSTRACT
OBJECTIVE: The differential diagnosis of renal disease is extensive. The purpose of this article is to enable the reader to recognize and understand the abnormal nephrographic patterns encountered in practice. CONCLUSION: Recognizing the different nephrographic patterns on CT urography can be invaluable in understanding the morphologic and physiologic condition of the kidney and ultimately diagnosing the disease process.

OBJECTIVE: Careful analysis of the nephrogram is an integral component of the evaluation of the kidneys during CT urography. This is a review of the anatomy and physiology required to produce a normal nephrogram, as well as the basic principles affecting the interpretation of the nephrogram. CONCLUSION: The eight abnormal nephrographic patterns will be illustrated and discussed. This review will enable the reader to recognize and understand the abnormal nephrographic patterns encountered in practice.
