title: Measurement of plasma contrast levels during excretory urography.
abstract: Ultraviolet spectrophotometry permits easy measurement of plasma levels of intravenously injected contrast media. The initial results are described from the determination of plasma methylglucamine iothalamate (Conray 60) levels during routine excretory urography in 10 normal patients. This simple procedure has many potential applications in the investigation of contrast media physiology.
