The persistent nephrogram: A sentinel sign of contrast reaction

J S Robbins 3rd et al. J Urol. 1975 Nov.

Abstract

Two cases are presented in which a serious contrast reaction was accompanied by a dense persistent nephrogram. This radiologic sign results from the patient's systemic hypotension and provides the physician with an opportunity for earlier, more effective therapy.
