Abstract

The nephrographic phase of the excretory urogram may be used to qualitatively assess some functional aspects of renal disease. Functional abnormalities of the kidney which alter the normal pattern of nephrographic opacification may be associated with renal perfusion abnormalities, glomerular dysfunction, intra or extrarenal obstruction, renal tubular necrosis and adverse reactions (renal or systemic) to iodinated contrast media. The time of maximum nephrographic opacification following intravenous injection of contrast medium and variations in nephrographic opacity before and after maximum opacification may help differentiate these disease processes. Standard radiographic and urographic techniques must be used to prevent changes caused by variations in contrast medium dosage and filming sequence from being misinterpreted as functional renal abnormalities.
