[The clinical value of sequential renal scans with 131 iodo-hipuran and renal perfusion with 99mtc compounds using computer analysis (author's transl)].
Two methods of sequential scintigraphy are considered critically: a) Quantitative computer evaluation of nephrograms obtained by a gamma camera using 131Iodo-Hipuran. b) Quantitative flow studies of the kidneys after bolus injections of 99mTc preparations. Statistical evaluation of data from 171 patients examined by both methods has shown that the isotope nephrogram is not sufficiently sensitive for diagnostic purposes. Isotope nephrography combined with estimations of effective renal plasma flow on each side separately is of value to the urological surgeon by providing important information regarding severe degrees of renal functional impairment. Perfusion measurements, using a gamma camera and 99mTc preparations, are a promising survey method for the diagnosis of renal artery stenosis. (Much of this work is contained in a dissertation by C. Knick).
