1954 P. G. Smith in M. Campbell Diagnostic Urol. x. 190 (caption) The exposure is made as the last few cc. of the contrast medium are being injected. The needle is immediately withdrawn and a second film is made as rapidly as the cassettes can be changed. This last film is known as a renogram or nephrogram.
