A graphical record of the varying radioactivity of a kidney into which a radioactive substance has been injected; also, a radiograph or autoradiograph of a kidney.
1954P. G. Smith in M. Campbell Urol. I. ii. ii. 189 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 The needle is immediately withdrawn and a second film is made as rapidly as the cassettes can be changed.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. 1964C. C. Webster in J. F. Glenn Diagnostic Urol. x. 190 (caption) The radioisotope renogram and blood clearance tracing are produced with three scintillation probes connected through three rate meters and three recorders. 1974Passmore & Robson Compar. Med. Stud. III. xxii. 16/1 When hippuran (sodium ortho-iodohippurate) labelled with 131I is given intravenously the substance is secreted rapidly into the proximal tubular fluid. Scintillation counters placed over the kidneys measure the radiation emitted by the isotope and the activity/time curve which is recorded is called the renogram. Ibid. 16/2 Patients with unilateral disturbances in renal function show differences in the shape and amplitude of the two renograms. |
